MUSCLE PHYSIOLOGY

Detailed explanation-1: -ATP synthesized in mitochondria is the primary energy source for important biological functions, such as muscle contraction, nerve impulse transmission, and protein synthesis.

Detailed explanation-2: -The majority of energy in an ATP molecule is stored in the bond between the last and middle phosphate groups.

Detailed explanation-3: -ATP (Adenosine tri-phosphate) is an important molecule found in all living things. Think of it as the “energy currency” of the cell. 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.
