The Energy Storage Molecule _______ Provides Energy for Muscle Contraction

Question

The energy storage molecule _______ provides energy for muscle contraction.
A) acetylcholine
B) acetylcholinesterase
C) ATP
D) glycogen

Accepted Answer

The energy storage molecule that provides energy for muscle contraction is adenosine triphosphate (ATP). ATP is produced through cellular respiration and stores energy in high-energy phosphate bonds. When a muscle fiber is stimulated, the ATP molecule is broken down, releasing energy that is utilized for muscle contraction.
