Homework Answers
Neurotransmitters are released from the synaptic vesicles and receptor proteins on the post-synaptic membrane receive them.
Neurotransmitters are chemicals that act as signalling molecules and transfer signals from a neuron to another neuron or target cell through synapse (neuronal junction). They are stored in synaptic vesicles and released at the synapse to transmit the signals. The signals released from synaptice vesicles (presynaptic membrane) at the junction are received and bind to the receptor proteins which are present in the post-synaptic membrane.
Calcium ions channels are present in the synaptic vesicles and regulate the release of neurotransmitters but are not released at the synapse. Therefore, first option (calcium ions and receptor proteins) is not the correct answer.
Voltage-gated calcium channels regulate the neurotransmitter release and membrane vesicles are part of exocytosis for their release at the synapse. Membrane vesicles do not receive signals (neurotransmitters) at the post-synaptic membrane. The neurotransmitters bind to the receptor proteins on the post-synaptic membrane. Therefore, third option (calcium ions and membrane vesicles) is not the right answer.
Neurotransmitters are released by synaptic vesicle but not received by membrane vesicles at the post-synaptic membrane. They are received by receptor proteins, therefore, option "neurotransmitters, membrane vesicle" is not the right answer.

Which of the following statements correctly characterizes synapses? Synaptic vesicles constitute important features for transmission in both chemical and electrical synapses A postsynaptic neuron typically receives input from different presynaptic axons that are either excitatory or inhibitory, but it cannot receive inputs from both types Synaptic delay is approximately the same for both chemical and electrical synapses Receptors can provide a gating function with respect to a given ion channel The mechanism of indirect gating of ions normally does not...
