Answer
Correct Answer: D. The molecule that releases energy when the phosphate molecule is removed
Detail about Mcqs
The correct answer is:
D. The molecule that releases energy when the phosphate molecule is removed.
Explanation:
ATP (adenosine triphosphate) is the primary energy currency of the cell.
It consists of three phosphate groups, and energy is stored in the high-energy bonds between these groups.
When a phosphate group is removed (via hydrolysis), ATP is converted to ADP (adenosine diphosphate) or AMP (adenosine monophosphate), and energy is released. This energy powers various cellular processes, including muscle contraction, active transport, and biosynthesis.
