What is the biological determination system for the sex of the baby

a. receptors that bind neurotransmitters trigger a change in postsynaptic membrane potential.

Explanation: Synaptic transmission is the communication between a neuron with another neuron. When the electrical impulse reaches the synaptic vesicles, they release their contents of neurotransmitters.

The neurotransmitters released into the synaptic cleft binds with the postsynaptic receptors and activates a receptor in the postsynaptic membrane. The binding of neurotransmitter results to the opening of channels in the neuron. Also, binding of neurotransmitters may influence the postsynaptic neuron in either an inhibitory or excitory way.

The binding of neurotransmitters to receptors in the postsynaptic neuron can trigger either short term changes or long-term changes.
