Answer 1

The synaptic modifications that would enhance postsynaptic neuron responses to glutamate release include triggering persistent activation of kinases, insertion of AMPA receptors, and increasing conductance across AMPA receptors.

Therefore, the correct options are:

• Triggering persistent activation of kinases

• Insertion of AMPA receptors

• Increasing conductance across AMPA receptors.

Step-by-step explanation:

Synapses are specialized sites where neurons connect and communicate with each other. Activity-dependent modification of synaptic structure and function provides a mechanism for learning and memory.

The synaptic modifications that would likely enhance postsynaptic neuron responses to glutamate release are:

• Triggering persistent activation of kinases: Kinases are enzymes that can phosphorylate AMPA receptors, thereby enhancing their conductance.

• Insertion of AMPA receptors: This increases the number of ion channels available for glutamate binding, enhancing the responsiveness of the postsynaptic neuron.

• Increasing conductance across AMPA receptors: Higher conductance allows a larger flow of ions, resulting in a stronger response to glutamate release.
