Question

neurotransmitter release is an example of ______ (1 point)
○ paracrine signaling
○ autocrine signaling
○ cyclical behavior
○ cellular miscommunication

Explanation:

Paracrine signaling involves cells releasing signaling molecules that act on nearby target cells. Neurotransmitters are released by neurons and bind to receptors on adjacent neurons, muscle cells, or gland cells, which fits the definition of paracrine signaling. Autocrine signaling acts on the same cell that released the signal, cyclical behavior refers to periodic cellular activities, and cellular miscommunication is an error in signaling, not the correct classification for normal neurotransmitter release.

Answer:

O paracrine signaling
