what is exocytosis
1 answer
Exocytosis is a cellular process through which materials, such as proteins or hormones, are transported out of a cell. It involves the fusion of vesicles, small membrane-bound sacs containing the desired substances, with the cell membrane. The contents of the vesicles are released outside the cell, allowing them to be utilized by other cells or tissues in the body. Exocytosis plays important roles in various physiological processes, such as the release of neurotransmitters at synapses, secretion of hormones, and export of digestive enzymes from the pancreas.
