The rate limiting reaction of aerobic respiration involves the phosphorylation of __________ by the enzyme _______ . The rate at which this enzyme makes product is ___________when ATP levels rise because the molecule ___________binds to an _________ site on the enzyme and acts as a(n)_________ . When ATP levels fall ________ binds to ________of ____________. This interaction leads to an increase of cellular ___________ , so that this is a n example of a ___________ feedback loop.
Answer:
Explanation:
The rate limiting reaction of aerobic respiration involves the phosphorylation of fructose phosphate by the enzyme phosphofructokinase. The rate at which this enzyme makes product is [increased, decreased] when ATP levels rise because the molecule ATP binds to an allosteric site on the enzyme and acts as a direct inhibitor. When ATP levels fall AMP binds to the allosteric site of phosphofructokinase. This interaction leads to an increase of cellular ATP, so that this is an example of a negative feedback loop.
An aerobic respiration can be defined as a chemical and biological process that involves the use of oxygen in living organisms to make energy (ATP) from carbohydrates (sugars) during cellular respiration.
This ultimately implies that, an aerobic respiration can take place or occur in the presence of oxygen.

What are the two main types of cells and where are they found in the human body?
Answer:
They are prokaryotes and eukaryotes and prokaryotes are single celled and eukaryotes are multi celled
Explanation:
Hope that helps! Have a fantastic day!
The two types of cells found in the human body are blood cells and immune cells.
What are cells?Cells are the fundamental foundations of all life. Trillions of cells make up the human body.
They support the body's structure, absorb nutrients from food, repurpose those nutrients into energy, and perform specialized functions.
Nucleic acids, proteins, carbohydrates, and lipids are the four major classes of organic compounds found in all cells.
A cell is made up of three parts: the cell membrane, the nucleus, and the cytoplasm that lies between the two.
The cytoplasm contains complicated accommodations of fine fibers as well as hundreds or even thousands of tiny but distinct structures known as organelles.
Thus, there can be many cells in a human body, the most important perhaps are blood cells and immune cells.

D
interphase
The cell cycle phase that occurs immediately following cytokinesis is the interphase, which is in Option D because the interphase consists of the G1, S, and G2 and is constitutively called the preparatory phase.
What is the cell cycle's importance?The cell cycle consists of the interphase and the division phase, and in the interphase, the cell spends most of the time preparing itself for the cell division and consists of the G1, S, and G2 phases. Following the interphase, the cell enters the division phase, which is mitosis or meiosis, and divides, with the daughter cells potentially entering the cell cycle via the interphase.
Hence, the cell cycle phase that occurs immediately following cytokinesis is the interphase, which is in Option D because the interphase consists of the G1, S, and G2 and is constitutively called the preparatory phase.

CFCs and other halogen-source chemicals in the stratosphere were discovered to deplete the ozone layer.
What is ozone layer depletion?
Ozone depletion is the steady lowering of the Earth's ozone layer in the high atmosphere, which is produced by the discharge of chemical compounds from industry and other human activities that contain gaseous chlorine or bromine.
The ozone layer acts as a buffer against the sun's potentially dangerous ultraviolet rays. The destruction of the ozone layer puts humans in direct contact with dangerous ultraviolet rays, which can lead to a variety of health problems including cancer, cataracts, skin illnesses, and a weakened immune system.

A) Identify a human disorder with developmental limitations that results from changes in chromosome number. Explain how nondisjunction leads to changes in chromosome number.
B) Mutations result in changes to genotype that can result in changes in phenotype. Explain how a mutation causes a change in the genotype of an organism AND may result in a change in the phenotype of an organism.
Answer:A) Patau Syndrome (Trisomy 13) causes intellectual and physical disability, such as underdeveloped eyes, extra fingers/toes, heart defects. Survival beyond the first year is uncommon.
B)
Explanation: Trisomy (or aneuploidy in general) can result when chromosomes to do not separate correctly during mitosis or meiosis. In meiosis, non-separation of a chromosome pair results in a gamete with two copies of the chromosome (and consequently one gamete lacking the chromosome.
At fertilisation the embryonic cell will have three copies of the chromosome (and an embryonic cell with one copy only). These are serious mutations, many of which are non-viable and usually abort spontaneously. Others results in abnormal development and poor survival rates. Only one autosomal trisomy (21) and sex chromosome trisomies (XXX, XXY etc) result in babies that survive into adulthood, albeit with physical and developmental abnormalities (trisomy 21 abd trisomy X). Only one monosomy (XO) is viable.
Other mutations can be less inimical, and may not result in any variation from normal. Mutations in genes coding for proteins or ribosomes may result in potential loss of function. As there are two copies of each gene, the mutated gene is paired with a normal gene and if that is expressed there will be no loss of function.
There are cases where the mutated gene is dominant it will change the phenotype. An example is Marfan Syndrome, an autosomal (chromosome 15) dominant mutation resulting in connective tissue abnormalities and long bones.
An autosomal recessive mutation is not expressed but is carried. If both parents are carriers, the probability of offspring to be doubly recessive and have an altered phenotype is 25%. Cystic fibrosis is an example.
A third possibility is where two alleles are co-dominant. An example of this is sickle cell disease. Consider the three allele pairs SS, Ss and ss.
Those with ss have sickle cell anaemia, a painful and debilitating condition. Those with SS have normal blood cells. Those with Ss have sickle cell trait, which has some mild deficits because a proportion of blood cells are abnormal.
Which of the following is false about DNA?
A. DNA is made up of units called nucleotides.
B. Any base can pair to any other base.
C. DNA contains the instructions to make proteins.
D. DNA is found in a cell's nucleus.
Answer:
b. any base pair can pair to any other base
Explanation:
Any base pair cannot pair with any other base, Adenine pairs with thymine and cytosine pairs with guanine.
• The hereditary material in humans and almost all of the living species is known as DNA or deoxyribonucleic acid.
• The majority of the DNA is present within the nucleus of the cell.
• DNA comprises the instructions to make proteins that helps to perform essential functions within the body of an organism.
• Within the DNA, information is stored in the form of a code formed of four chemical bases, that is, Adenine, guanine, cytosine, and thymine.
• The base pairs present within the DNA pairs up with each other, that is, adenine pairs with thymine only, and guanine pairs with cytosine, no other kind of pairing is found within the DNA. Each base of also attached with a molecule of phosphate and sugar.
• Together, a phosphate, base, and sugar are known as a nucleotide.

What would happen if a cell couldn't make catalase?
Answer:
If hydrogen peroxide is not broken down by catalase, additional reactions convert it into compounds called reactive oxygen species that can damage DNA, proteins, and cell membranes. ... A shortage of this enzyme can allow hydrogen peroxide to build up to toxic levels in certain cells
If hydrogen peroxide is not broken down by catalase, it can be converted into reactive oxygen species, which can damage DNA, proteins, and cell membranes.
What is catalase?Catalase is an important enzyme that uses hydrogen peroxide, a non-radical ROS, as a substrate.This enzyme breaks down and neutralizes hydrogen peroxide to maintain optimal molecular levels within cells.It is also essential for cell signaling processes. The catalase enzyme breaks down hydrogen peroxide (H2O2) into water and molecular oxygen, protecting cells from oxidative damage by reactive oxygen species.Commercially available catalase is produced from Aspergillus niger by a solid-state fermentation process.Peroxidase or catalase is an enzyme of the oxidoreductase class. The peroxidase enzyme catalyzes the breakdown of hydrogen peroxide into water and molecular oxygen as shown.Catalase is a tetrameric heme protein that detoxifies H2O2 into oxygen and water.It is a metalloprotein oxidoreductase and when present in high concentrations he efficiently removes H2O2.To learn more about catalase, refer

4. Take a beaker (jar or jug) with some water and put some drops of red or blue
ink in it. Take a tender twig of any flowery plant with leaves and flowers, preferably
white flowers, and put it in the beaker for 6 to 8 hours. What do you observe? For
further examination cut across its stem and look for the presence of colored water.
Explain your observations.
Answer:
Blue Ink patches are observed on the leaves of the plant. Also, on cutting across the stem of the plant, the red color of the solution is found along the length of the stem.
The above observation shows that the stem of the plant conducts water through its length to the leaves of the plant.
Explanation:
The leaves of plant obtain water and minerals from the soil through the roots of the plant. The water is conducted by the stem of the plant from the roots to the leaves of the plant where they are needed for photosynthesis as well as for cooling the plant. The xylem tissue in plants is responsible for conducting water to the leaves of the plant from the roots of the plant through the stem.
The conduction of water from the roots to the leaves of the plant is maintained by capillary action as well as by transpiration pull. Transpiration pull refers to the pull of water by the transpiration action taking place in the leaves of the pant, whereby water evaporates from the leaves of the plant through the opening in the leaf of the plant.
When the blue ink is added to the water, the colored water is conducted through the stem of the plant to the leaves. On getting to the leaves, the water molecules evaporate leaving behind the colored patches fond on the leaves. When the stem of the plant is cut, the blue color is seen along its length showing that the colored water was conducted through it.
