What is the role of dendrites in the process of neurotransmission?

Dendrites pick up the message from the previous cell (correct)
Dendrites convert electrical impulses into chemical signals
Dendrites release neurotransmitters into the synapse
Dendrites store genetic information in the nucleus

In the process of neurotransmission, what occurs at the presynaptic terminal?

Neurotransmitters are converted into electrical impulses
Voltage-gated calcium channels release neurotransmitters
The action potential is converted into a chemical signal (correct)
Genetic information is stored for future use

What is the function of voltage-gated calcium channels in neurotransmission?

Regulate the release of neurotransmitters at the presynaptic terminal (correct)
Convert chemical signals into electrical impulses
Convert electrical impulses into chemical signals
Store genetic information for future use
