Among the agents that can cause ryanodine receptors to open are _______ ions, in a phenomenon called _______.
A)calcium, calcium-integrated calcium release
B)calcium, calcium-induced calcium release
C)potassium, potassium-induced calcium release
D)chlorine, chlorine-induced calcium release
E)copper, copper-induced calcium release

Question

Quizplus · Accepted Answer

Ryanodine receptors are calcium-release channels found in muscle cells. When calcium ions bind to the receptors, they cause the channels to open, allowing more calcium ions to flow into the muscle cell. This phenomenon is known as calcium-induced calcium release. Potassium and chlorine ions do not directly stimulate the opening of ryanodine receptors. Copper ions are not typically involved in calcium signaling.
