Contraction of striated muscle is regulated by
A)TnC's affinity for Ca²⁺ (and nothing else).
B)alternating the two available isoforms of myosin.
C)utilizing different combinations of muscle protein isoforms.
D)the rate at which Ca²⁺ is able to bind to actin.

Question

Quizplus · Accepted Answer

Contraction of striated muscle is regulated by the interaction of actin and myosin, which is influenced by the binding of calcium to troponin, and the utilization of different combinations of muscle protein isoforms can affect muscle contraction properties.
