Question

How does inositol triphosphate (IP3) contribute to calcium signaling within cells?

Accepted Answer

IP3 binds to receptors on the endoplasmic reticulum, causing calcium release into the cytoplasm.

Answer

IP3 directly activates protein kinase C, which then opens calcium channels.

Answer

IP3 inhibits calcium uptake into the mitochondria, increasing cytoplasmic calcium levels.

Answer

IP3 is converted into cyclic AMP, which then opens calcium channels.
