Question

Which of the following is/are a function(s) of sarcoplasmic reticulum?

• A. Store calcium
• B. Release calcium
• C. Allow impulses to permeate the cell membrane
• D. None of the above

Answer 1

Answer: (A), (B)

The correct options are
A Store calcium
B Release calcium

The function of the sarcoplasmic reticulum is to store and release calcium ions in the body's muscle cells.
Transverse tubules exist in plasma membranes within skeletal muscle and cardiac muscle cells. In the process of creating invaginations, transverse tubules allow impulses to permeate the cell membrane, and ultimately excite, or activate, the sarcoplasmic reticulum.
