How would a calcium deficiency affect the process of skeletal muscle contraction?
A) Myosin heads would not bind to actin efficiently.
B) The action potential would be blocked from entering the muscle fiber.
C) The myosin heads would remain attached to actin molecules.
D) Skeletal muscles would not be able to utilize ATP as a source of fuel.

Question

Quizplus · Accepted Answer

Calcium ions are crucial for muscle contraction as they bind to troponin, causing a conformational change that moves tropomyosin away from actin's binding sites, allowing myosin heads to bind to actin efficiently. Without calcium, this process is hindered.
