Muscle contractions often need to happen quickly so they are controlled via _____________ receptors.

Question

Quizplus · Accepted Answer

Ionotropic receptors directly gate ion channels and mediate fast neurotransmission, making them the best choice for muscle contractions that need to happen quickly. Metabotropic receptors are G protein-coupled receptors that typically mediate slower neurotransmission and modulate ion channels indirectly. Serotonergic and dopaminergic receptors are specific types of neurotransmitter receptors that are not inherently faster or slower than ionotropic or metabotropic receptors. Synthetic receptors are not a recognized category of neurotransmitter receptors.
