Chapter 2, Problem 5MCQ
Summary Introduction
Introduction:
Adenosine triphosphate (ATP) is a high energy compound. ATP synthesized from the mitochondria by the process of oxidative phosphorylation. Cells get energy by hydrolysis of ATP and breakdown of phosphate bond. ATP is the main compound to release energy for muscle contraction.
