Final answer:

Ca2+-ATPase pumps actively transport calcium back into the sarcoplasmic reticulum.

Step-by-step explanation:

The pumps that actively transport calcium back into the sarcoplasmic reticulum are called Ca2+ -ATPase pumps. These pumps play a crucial role in muscle contraction and relaxation. When calcium ions are actively transported out of the sarcoplasmic reticulum, muscle contraction can occur.
