One ATP molecule is required for
A) formation of the cross-bridge.
B) movement of the cross-bridge.
C) release of the cross-bridge.
D) formation of the cross-bridge and for movement of the cross-bridge.
E) formation of the cross-bridge, for movement of the cross-bridge, and for release of the cross-bridge.
ATP Molecule
Adenosine triphosphate, the primary carrier of energy in cells, facilitating energy transfer by undergoing enzymatic hydrolysis.
Cross-Bridge
The link formed between the actin and myosin filaments in a muscle fiber that generates contraction by shortening the muscle.
- Understand the basic mechanisms of muscle contraction and relaxation.
- Identify the biochemical steps involved in muscle contraction.

Final Answer :
E
Explanation :
One ATP molecule is required for all three processes involved in muscle contraction: formation of the cross-bridge, movement of the cross-bridge, and release of the cross-bridge. ATP provides the energy necessary for these steps, enabling the muscle to contract and relax.
