Final answer:
The pumps that actively transport calcium back into the sarcoplasmic reticulum are called Ca2+-ATPase. Ca²⁺-ATPase pumps actively transport calcium back into the sarcoplasmic reticulum, using ATP to move ions against their gradient, crucial for muscle function.
Step-by-step explanation:
The pumps that actively transport calcium back into the sarcoplasmic reticulum are called Ca2+-ATPase. These pumps play a crucial role in muscle contraction and maintaining muscle tone.
Ca²⁺-ATPase pumps actively transport calcium back into the sarcoplasmic reticulum, using ATP to move ions against their gradient, crucial for muscle function.
The pumps that actively transport calcium back into the sarcoplasmic reticulum (SR) are called Ca²⁺-ATPase. These pumps are involved in muscle contraction and relaxation processes. The Ca²⁺-ATPase is an example of primary active transport because it uses ATP directly to move calcium ions against their concentration gradient, from the cytosol back into the SR, where they are stored for future use in muscle contractions. These pumps play a crucial role in resetting the muscle following contraction and ensuring that intracellular calcium levels are maintained at the appropriate levels necessary for muscle function.
