Acetylcholine binds to (5HT/cholingeric/adrenergic) receptors. Nicotinic receptors are ionotropic and (decrease release of neurotransmitter/ open a ion channel directly/ activate a g protein coupled receptor/increase release of neurotransmitter) while muscarinic receptors are metabotropic and (decrease release of neurotransmitter/ open a ion channel directly/ activate a g protein coupled receptor/increase release of neurotransmitter )

Answer #1

Answer:

Acetylcholine binds to cholingeric receptors. Nicotinic receptors are ionotropic and open a ion channel directly while muscarinic receptors are metabotropic and activate a g protein coupled receptor.

Explanation:

Acetylcholine binds to its receptor known as acetylcholine receptor (AChR) which is cholingeric receptor.

There are two type of acetylcholine receptor (AChR)— nicotinic acetylcholine receptor (nAChR) and muscarinic acetylcholine receptor (mAChR).

Nicotinic acetylcholine receptors (nAChR) are ionotropic and open a ligand-gated ion channel directly while muscarinic receptors (mAChR) are metabotropic and activate a G-protein coupled receptor.

Acetylcholine binds to a G-coupled protein receptor on the heart muscle to make the heart beat more slowly. It does so by stimulating the opening of K+ channels in the plasma membrane, which makes it more difficult to initiate and action potential. Describe the following on contraction of the heart. A.) Addition of a drug that inhibits the GTPase activity of the Ga subunit. B.) Mutations in the K+ channel that keep it closed all the tiem. C.) A mutation...

1. Receptor A and Receptor B are both G-protein coupled receptors (GPCRs), expressed in the same cell, but they control different biological responses. Receptor A and Receptor B are known to bind and respond to Hormone A and Hormone B, respectively. Treatment of the cells in the laboratory with Hormone A and B revealed that activation of Receptor A results in a dramatic increase in cyclic-AMP levels in the cell, while activation of Receptor B results in increased inositol triphosphate...
