Question

Quizplus · Accepted Answer

T-tubules carry the stimulus to contract the muscle inside the muscle.

Answer: F
 Calcium is responsible for uncovering the binding site on actin, allowing myosin to attach and initiate muscle contraction.

Answer: G
 Cross-bridges form between myosin and actin during muscle contraction.

Answer: I
 Acetylcholine is the neurotransmitter that stimulates muscle contraction.

Answer: E
 ATP is required for the detachment of myosin from actin during muscle relaxation.

Answer: A and H
 Troponin and tropomyosin work together to regulate the binding site on actin and prevent muscle contraction when not needed.
