Production and Transport of Materials in Secretory Vesicles Which Occurs

Question

Production and transport of materials in secretory vesicles which occurs continuously is known as:
A)regulated secretion
B)endogenous secretion
C)exogenous secretion
D)constitutive secretion

Accepted Answer

Constitutive secretion is the continuous production and transport of materials in secretory vesicles, without the need for a specific stimulus or regulation. This differs from regulated secretion, which requires a specific signal or stimulus to trigger the release of stored materials from secretory vesicles. Endogenous and exogenous secretion refer to the source of the secreted material (internally produced or externally acquired, respectively) and are not related to the continuous or regulated nature of secretion.
