Cell signaling between two nerve cells can be thought of as an example of paracrine signaling because:
A)a signaling molecule (neurotransmitter)is released.
B)a receptor is activated.
C)the cells are in close proximity.
D)the responding cell releases more of the signaling molecule (neurotransmitter).

Question

Paracrine signaling involves the release of signaling molecules that affect nearby target cells. In the context of two nerve cells communicating, the key aspect is their close proximity, which allows for the direct influence of one cell on another through the synaptic gap.
