Document Summary

Receptors for direct and indirect effects: ionotropic receptor. Embedded membrane protein with two parts: a binding site for a neurotransmitter, a pore that regulates ion flow to directly and rapidly change membrane voltage. Receptors for direct and indirect effects: metabotropic receptor. Embedded membrane protein with a binding site for a neurotransmitter but no pore. Linked to a g-protein that can affect other receptors or act with second messengers to affect other cellular processes: g-protein. Family of guanyl nucleotide-binding proteins coupled to metabotropic receptors that, when activated, bind to other proteins. Receptors for direct and indirect effects: second messenger. Activated by a neurotransmitter (the first messenger) A chemical that carries a message to initiate a biochemical process: examples. Alter ion flow in a membrane channel. Neuron that uses acetylcholine (ach) as its main neurotransmitter. Excites skeletal muscles to cause contractions: nicotinic ach receptor.
