Homework Answers
D is the correct option.
IP3 binda to its receptor which is located on calcium ion channels of endoplasmic reticulum membarane. When IP3 binds with receptor which caused opening of calcium ion gated channels and calcium ions moves in to cytoplasm from endoplasmic reticulum. Calcium ions activate the so many calcium mediated signal for metabolic reaction.
In case of metabotropic receptors are coupled to the phospholipase C which activate the synthesis of IP3 and DAG.
GPCRs are present on the extracellular domen of ligand receptors like adrenaline. When first messenger bind with GPCR it caused confirmation change and activation of G protein which activate various type of enzyme like adenylate cyclase .
Tyrosine kinase responsible for synthesis of IP3 which bind with IP3 receptor of endoplasmic reticulum.
Add Answer to:
Receptors that bind IP3 are generally metabotropic receptors GPCRs receptor tyrosine kinases ligand-gated ion channels

When neurotransmitters bind to metabotropic receptors, they bind to the _________ of the receptor, causing the receptor to change shape, which is the first step in an intracellular signaling cascade. One essential neurotransmitter, acetylcholine, can generally exert excitatory effects when binding to its ionotropic receptors but can have either excitatory or inhibitory effects when binding to _____________ receptors. When neurotransmitters like acetylcholine bind to _________ receptors they let ions (e.g. Na+, Cl-) into the neuron directly through that channel they...
