C)Ampakine
D)AMPA

Question

Quizplus · Accepted Answer

CaMKII, or calcium/calmodulin-dependent protein kinase II, is thought to act as a binary switch that changes the strength of a synapse. It is activated by calcium influx during synaptic activity and can phosphorylate AMPA receptors, leading to their insertion into the postsynaptic membrane and the strengthening of the synapse. LTP (long-term potentiation) is a form of synaptic plasticity that involves the strengthening of synaptic connections, but it is not a molecule that acts as a binary switch. Ampakines are drugs that enhance the activity of AMPA receptors, and AMPA receptors are a type of glutamate receptor that is important for synaptic transmission, but neither of these directly act as a binary switch.
