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 correct sequence for the process of forming a human embryo in the diagram above is gamete formation, fertilization, and then the cell division. The process that is correct is number 3.
The daughter cells are identical to the original cell.
