What is the function of enzymes in a living system?
Enzymes speed up metabolic reactions necessary for life. Without them, certain vital processes would not take place and the body would be unable to function.
Difference enzymes work better under different conditions. Where in a human body might it be beneficial to have enzymes work in very acidic environments?
In areas, like the stomach, that have a pH of two would benefit by having enzymes that function well in acidic environments. An example of such an enzyme is pepsin.
There is a large amount of catalase found in a human liver. Does the liver break down more hydrogen peroxide in the summer or winter? Explain your answer.
More hydrogen peroxide will be broken down in the summer…show more content…
Potassium permanganate - used to titrate and determine the amount of decomposed hydrogen peroxide.
Sulfuric acid - was used to stop the reaction with catalase and hydrogen peroxide. It denatured the enzyme (catalase) and halted the reaction so the amount of hydrogen peroxide decomposed could be measured.
Before performing part D of the experiment, why was it necessary to establish a baseline?
The baseline is a control and shows the amount of decomposed hydrogen peroxide in the initial sample.
You may have observed the reaction of naturally occurring catalase in tissue from either liver or potato. Design an experiment to determine if the amount of catalase varies from tissue to tissue (e.g. 200 g of the liver compared to 200 g of potato).
Put the 100 g of potato in 1 petri dish and 100 g of the liver in another petri dish. Then put equal amounts of hydrogen peroxide for an equal period of time in both dishes. Drain the dishes and titrate them with potassium permanganate simultaneously. The numbers can now be compared using the steps in the sample calculation above in the lab report. In order to compare perform a potassium permanganate titration on pure hydrogen peroxide.
Of the thousands of enzymes known, there is a family of enzymes called proteases that catalyze a reaction of breaking down proteins. What do you think would happen if you added a protease to your sample of catalase before proceeding with your experiment?
The catalase would be broken
Which of the following statements are NOT true of micronutrients? a) They help regulate body processes.
b) They provide energy.
c) They help in the growth and maintenance of the body.
d) They are required in small amounts
Answer:
C
Explanation:
its easy
b)They provide energy statements are NOT true of micro nutrients
Do micronutrients control bodily functions?
Every single micronutrient is crucial for the health of your body's systems. Getting enough of the various vitamins and minerals is essential for good health and could even aid in the prevention of disease.
This is due to the fact that micronutrients are involved in almost every bodily process.
One of the most important vitamin categories that your body need are micronutrients. They contain minerals and vitamins. The creation of energy, immune system health, blood coagulation, and other processes all depend on vitamins.
In the meanwhile, minerals are crucial for a number of functions, including growth, bone health, fluid balance, and others.

[tex] \huge \mathfrak{{ \pmb{ \underline{ \red{Answer}}}}}[/tex]
The red blood cells and brain are two body tissues that derive most of their energy from glucose.
Glucose is the answer.
The red blood cells and brain are two body tissues that derive most of their energy from carbohydrates. The correct option is C.
What are carbohydrates?Sugar molecules make up carbohydrates, or carbs. Carbohydrates are one of the three primary nutrients included in foods and beverages, along with proteins and fats.
Glucose is created by your body's breakdown of carbs. The primary source of energy for the cells, tissues, and organs in your body is glucose, sometimes known as blood sugar.
Under normal conditions, glucose serves as the brain's main energy source.
Using either glycolysis or oxidative phosphorylation—the latter of which is 15 times more efficient—glucose is used to create energy in the form of adenosine triphosphate (ATP).
In the absence of glucose, the brain has backup energy sources, such as ketones created by fatty acid metabolism, which predominantly takes place in the liver.
These include 3-hydroxybutyrate, acetone, and acetoacetate (3BHM).
Thus, the correct option is C.

The Centers for Disease Control (CDC) collect vast amounts of data. For this activity, we want you to use their Natality Information database to test various hypotheses about birth. For the following five issues, please create a hypothesis and then use the database to collect information about the issue. Once you the data is displayed, record it and indicate whether your hypothesis was supported by data.
The database functions in this manner:
Upon going to this website, you will need to comply with the CDC requirements for using the database. Because this is a school activity, you will be fine. Click I Agree.
The top section (Section 1) of the query engine will allow you to determine how your data sets will be displayed. You will want to Group Results by State for the queries you will perform.
Be sure to select the correct measure for your question/hypothesis. Select only one measure for each query.
Section 2 allows to select individual states or multiple states for comparison. If you have selected states in Section 1, you can run multiple data sets here and see them displayed by state. If you did not, the only way to see individual state data is to run the query one state at a time.
The remaining sections include the conditions you can use for comparison. You will need to find the appropriate section for the condition you are testing for. Once you have found it, go ahead and run your query by clicking Send.
Let me talk you through the process. Seriously, watch this video explanation of what you're doing.
Here's an example. Which state, Utah or New York, has the highest average age for mothers giving birth?
Hypothesis: New York has the highest average age for mothers giving birth.
Data (based on the following settings)
Section 1: Group Results by State; Measure: Average Age of Mother (years)

Letter C marks the second integral membrane protein complex. Letter D marks a substance inside the thylakoid. Letter E indicates a flask-shaped structure in the membrane of the thylakoid, which has a canal through the membrane. D B C A E
The luminous reactions begin when light reaches photosystem II. The water molecules provide electrons to the photosystem, releasing oxygen and protons. The letter A represents photosystem II that splits water.
-----------
1. Luminous energy is trapped by chlorophyll in Photosystem II.
2. When the pigment molecules absorb light, electrons provided by water molecules get in a higher energy level.
3. The excited electrons go through the electron transport chain from Photosystem II to a less energetic level in photosystem I.
4. When the excited electrons leave photosystem II, they are replaced by new electrons extracted from the water molecules.
5. Luminous energy absorbed move the electrons from the photosystem I to another electron acceptor, from where they get transported again and used to produce NADPH molecules.
6. When electrons leave Photosystem I, they are replaced by new electrons coming from photosystem II.
7. When the water molecule breaks down, hydrogen ions remain in the thylakoid lumen, from where they are pumped to the stroma by the ATP synthase.
8. The released energy is used to produce ATP molecules.
9. Hydrogen ions go back from the stroma to the thylakoid compartment.

A way you could test if bacteria are different is through Gram Staining
Despite all bacteria are prokaryotic organisms, there are thousands of bacteria species and each species has different characteristics.
Moreover, bacteria are classified into two main groups:
Gram-negative bacteriaGram-positive bacteriaThese differ in their structure as gram-positive bacteria have a thick peptidoglycan layer, while gram-negative bacteria have a thin peptidoglycan layer and an external layer.
This key difference is essential when classifying bacteria because there are specific species for each type. Moreover, this can be tested through Gram staining, as this will show gram-positive bacteria as purple and gram-negative ones as pink or red.
