Muscle contraction kinetics can be affected by
A)affinity of troponin for Ca²⁺.
B)pH.
C)temperature.
D)all of the above

Question

Quizplus · Accepted Answer

All of the above (affinity of troponin for Ca²⁺, pH, temperature) can affect muscle contraction kinetics. The affinity of troponin for Ca²⁺ affects the availability of Ca²⁺ ions which bind to troponin and initiate muscle contraction. pH can affect muscle contraction by altering the conformation of proteins involved in contraction. Temperature affects the rate of enzymatic reactions involved in muscle contraction.
