Question
The secretion of a signal molecule by a cell into the local environment, followed by a response by a number of cells in the immediate vicinity, is an example ofGroup of answer choiceshormonal signalingparacrine signalingendocrine signalingsynaptic signaling
Solution
The example given describes paracrine signaling. In paracrine signaling, a cell produces a signal to induce changes in nearby cells, altering the behavior or differentiation of those cells. This type of signaling only affects cells in the immediate vicinity of the emitting cell. Hormonal signaling (endocrine signaling) involves signals (hormones) that are transported in the bloodstream and can have effects on distant cells. Synaptic signaling is specific to neurons in the nervous system.
