Calcium-induced calcium release occurs when A) Ca²⁺ from the sarcoplasmic reticulum stimulates the movement of Ca²⁺ into the cell through the plasma membrane. B) Ca²⁺ is released from both the sarcoplasmic reticulum and the cardiac muscle cell. C) the eflux of Ca²⁺ from the cell results in depolarization. D) Ca²⁺ entering through the plasma membrane stimulates release of Ca²⁺ from the sarcoplasmic reticulum.

Question

Quizplus · Accepted Answer

Calcium-induced calcium release refers to the process where calcium entering the cell through the plasma membrane triggers the release of additional calcium from the sarcoplasmic reticulum, amplifying the calcium signal within the cell.
