When muscle tissue is exercising under anaerobic conditions, the production of ______ is important because it ensures a continuous supply of NAD

Answers

Given what we know about the biological mechanisms behind anaerobic exercise, we can confirm that the production of lactate ensures a continuous supply of NAD.

In order for us to undergo any physical exercise, it is imperative that we are able to produce energy within our cells. The energy used by cells is in the form of a molecule by the name of ATP, which is produced primarily through a process known as Glycolysis.

This is relevant given that in order for glycolysis to happen, a key protein is required known as NAD+. Lactate is produced from pyruvate only under anaerobic conditions because these are conditions that lack oxygen which is the only other source of NAD+, therefore, pyruvate must be converted to lactic acid to make it possible to continue glycolysis and the production of ATP.

Does the waxy cutie affect where acertain pla y could be grown? Why?

Answers

Waxy skin - some leaves have a thick, waxy skin on their surface. This reduces water loss by transpiration . Water storage - some plants, known as succulents, store water in their stems, leaves, roots or even fruits.

The waxy covering on plant leaves, young stems, and fruit is called the "cuticle". ... The purpose of this covering is to help the plant retain water. In arid regions, that is very important. In wetter regions, the waxy coating may help prevent infection by disease organisms.

Plants that grow in arid zones of USDA zones 9 to 11 use waxy leaves to limit transpiration and retain water but also to protect leaves from the frigid temperatures sometimes found in the desert. Trees like the desert willow (Chilopsis linearis) have narrow, waxy leaves and striking purple flowers.

Nitrogen-fixing bacteria in the ground

Answers

Answer: 3

Explanation:

Nitrogen, the most abundant element in our atmosphere, is crucial to life. Nitrogen is found in soils and plants, in the water we drink, and in the air we breathe. It is also essential to life: a key building block of DNA, which determines our genetics, is essential to plant growth, and therefore necessary for the food we grow. But as with everything, balance is key: too little nitrogen and plants cannot thrive, leading to low crop yields; but too much nitrogen can be toxic to plants, and can also harm our environment. Plants that do not have enough nitrogen become yellowish and do not grow well and can have smaller flowers and fruits. Farmers can add nitrogen fertilizer to produce better crops, but too much can hurt plants and animals, and pollute our aquatic systems. Understanding the Nitrogen Cycle—how nitrogen moves from the atmosphere to earth, through soils and back to the atmosphere in an endless Cycle—can help us grow healthy crops and protect our environment.

The release of one phosphate group from ATP powers the reactants in the cell which phosphate is the one that is released from ATP

Answers

Answer:

ADP

Explanation:

Your question: The release of one phosphate group from ATP powers the reactants in the cell which phosphate is the one that is released from ATP

My answer: ADP

Why is my answer correct?

If a cell needs to spend energy to accomplish a task, the ATP molecule splits off one of its three phosphates, becoming ADP (Adenosine di-phosphate) + phosphate. The energy holding that phosphate molecule is now released and available to do work for the cell.

19. Engineer It In some rivers and lakes, dams
are constructed to harvest energy by converting the
kinetic energy of moving water into electrical energy.
Water from behind the dam flows through a turbine
that transforms kinetic energy into mechanical
energy. The turbine turns a generator that converts
mechanical energy into electrical energy.
The water from behind the dam could flow to the
turbine either through an opening near the middle or
top of the dam or by flowing over the top of the dam.
Which type of water flow would be the best design for
sending a consistent flow of water past the turbines?
Explain your reasoning.

Answer:

A hydroelectric dam converts the potential energy stored in a water reservoir behind a dam to mechanical energy—mechanical energy is also known as kinetic energy. As the water flows down through the dam its kinetic energy is used to turn a turbine.

The effect of pH on a certain enzyme is shown in the graph. At what pH would the enzyme be most effective?

Answers

Answer:

2

Explanation:

The enzyme will be the most effective between 8 and 10

The enzyme will show maximum activity in the range of pH between 8 and 10. This can be the enzyme's optimum pH as at this range it is found to be most effective. Thus, the correct option is 2.

What are enzymes?

Enzymes are the biocatalysts. They act as enzymes in the biochemical reactions by reducing the activation energy required by the reactants to form products. Enzymes remain unused in a reaction.

Enzyme activity depends upon different factors which include temperature, pressure, pH, etc. Enzymes show maximum activity at the optimum conditions of these environmental factors.

From the given graph, it can be interpreted that the enzyme shows maximum rate of action between the pH range of 8 and 10. Thus, this is the optimum range of pH.

Therefore, the correct option is 2.
