E) Inositol triphosphate can open an ion channel, releasing calcium into the cytoplasm.

Question

Quizplus · Accepted Answer

Inositol triphosphate (IP3) is released from the membrane after phospholipase C catalyzes its formation. It acts as a second messenger by binding to receptors on the endoplasmic reticulum, causing the release of calcium into the cytoplasm. IP3 does not remain bound to the membrane. Therefore, statement D is false.
