Which of the following pumps is specifically used to return Ca²⁺ to the sarcoplasmic reticulum?
A)Ca²⁺ATPase
B)NaCaX
C)parvalbumin
D)SERCA

Question

Quizplus · Accepted Answer

SERCA (Sarcoplasmic/Endoplasmic Reticulum Calcium ATPase) pump is specifically responsible for transporting Ca²⁺ ions from the cytoplasm back to the sarcoplasmic reticulum in muscle cells. The other options, such as Ca²⁺ATPase, NaCaX, and parvalbumin, may be involved in Ca²⁺ transport but not specifically in the return of Ca²⁺ to the sarcoplasmic reticulum.
