In striated muscle contraction,the Ca2⁺-ATPase pump A)releases Ca2⁺ from the T tubule. B)secretes Ca2⁺ from the axon terminal. C)is voltage-gated. D)decreases Ca2⁺ in the sarcoplasm. E)increases Ca2⁺ binding to TnC.

Question

Quizplus · Accepted Answer

The SERCA (Sarco/Endoplasmic Reticulum Ca2+-ATPase) pump decreases Ca2+ in the sarcoplasm by pumping it back into the sarcoplasmic reticulum, thus helping to end muscle contraction.
