Question

question 24 (2 points) listen the primary role of calcium in a muscle is to allow the muscle to perform anaerobically serve as metabolic fuel for the muscle cause the breaking of muscle cross - bridges expose the binding sites between muscle filaments, allowing cross bridges to form serve as a neurotransmitter to stimulate the muscle previous page next page page 24 of 42

Explanation:

Calcium ions bind to troponin - C in muscle cells. This causes a conformational change in the troponin - tropomyosin complex, exposing the binding sites on actin filaments for myosin heads, enabling cross - bridge formation and muscle contraction.

Answer:

expose the binding sites between muscle filaments, allowing cross bridges to form
