Question

Adenosine triphosphate (ATP) is an important molecule because it _______. a. is the result of catabolism b. releases energy in uncontrolled bursts c. provides energy for use by body cells d. All of the above

Short answer

Question: Adenosine triphosphate (ATP) is an important molecule because it: a) is the result of catabolism b) releases energy in uncontrolled bursts c) provides energy for use by body cells d) All of the above Answer: c) provides energy for use by body cells

Step-by-step solution

Understand the options#a.

First, let's look at each option: a) ATP is the result of catabolism b) ATP releases energy in uncontrolled bursts c) ATP provides energy for use by body cells d) All of the above

Option A#a.

Catabolism is the set of metabolic pathways that break down large molecules into smaller ones, releasing energy in the process. The production of ATP is one of the main purposes of catabolism. Therefore, this statement can be considered true.

Option B#a.

The release of energy from ATP is, in fact, controlled. When broken down by cellular enzymes, it releases a manageable amount of energy that cells can use to power their processes. Thus, option B is false.

Option C#a.

When ATP is hydrolyzed (broken down) by cellular enzymes, one phosphate group is removed, and the energy stored in the bond is released. This energy is then used by the body's cells to perform various functions, such as muscle contractions, protein synthesis, and cell division. This option is true.

Option D#a

Option D states that all above statements are true. As we have shown before, option B is actually false. So, option D is incorrect.

Choose the correct answer#a.

From our evaluation, we can conclude that the answer is option C - "Adenosine triphosphate (ATP) is an important molecule because it provides energy for use by body cells."
