MEDICAL PHYSIOLOGY

Detailed explanation-1: -ATP hydrolysis provides the energy needed for many essential processes in organisms and cells. These include intracellular signaling, DNA and RNA synthesis, Purinergic signaling, synaptic signaling, active transport, and muscle contraction.

Detailed explanation-2: -Muscle contraction occurs via metabolism of adenosine triphosphate (ATP) derived primarily from the simple sugar glucose.

Detailed explanation-3: -During contraction, the creatine phosphate breaks into creatine and releases phosphorous which combine with ADP to form ATP. The ATP formed is used up by the muscles for contraction.

Detailed explanation-4: -Adenosine triphosphate (ATP) is the sole fuel for muscle contraction.
