Question

Which of the following supplies the energy required for muscle contractions?

a. myosin
b. atp
c. acetylcholine
d. actin

Answer 1

ATP supplies the energy required for muscle contractions so the answer is letter B. Adenosine Triphosphate is responsible also in ATP synthesis which gives energy in the process of photosynthesis just to form glucose which is needed in the storage of energy in the body.

Answer 2

The correct option is B.
ATP is the energy currency of the biological system, it is the only chemical compound that the human system can used to provide the necessary energy needed to carry out life processes.Thus, ATP supplies the energy needed for muscle contraction to take place; when the muscles run out of ATP, they stop contracting and become fatigued.
