MICROANATOMY

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

Detailed explanation-3: -Muscle contractions are fueled by adenosine triphosphate (ATP), an energy-storing molecule.

Detailed explanation-4: -The rate of ATP breakdown ranges from 70 to 140 mM min-1 during isometric contractions of various intensity to as much as 400 mM min-1 during intense, dynamic activity.
