Answer:
Active transport of calcium into the sarcoplasmic reticulum.
Explanation:
- The sarcoplasmic reticulum (SR) is a membrane-bound structure found within muscle cells that is similar to the endoplasmic reticulum in other cells. The main function of the SR is to store calcium ions (Ca2+)
- In response to an action potential traveling along the t tubule, voltage-sensitive proteins change shape, opening calcium channels in the adjacent terminal cisterns of the sarcoplasmic reticulum.
The reason why eukaryotic cells are in need of turning on
and off their genes when necessary because of the reason that they may feel
stress because they are under stress as they have the responsibility of acting
immediately when they needed and by that, they need to be turned on or off in means
of adapting to the stress that they experience.
