A skeletal muscle with abnormally low levels of calcium ions would be impaired in
A) ATP hydrolysis.
B) the initiation of an action potential.
C) maintaining its resting membrane potential.
D) initiating contraction.
E) its ability to sustain glycolysis.

Question

Quizplus · Accepted Answer

Calcium ions play a critical role in triggering muscle contraction by binding to troponin and initiating a conformational change that allows myosin to bind to actin. Therefore, a skeletal muscle with abnormally low levels of calcium ions would be impaired in initiating contraction.
