Which the following descriptions would be an example of exocytosis? Which the following descriptions would be an example of exocytosis? A. a macrophage imbibing its surrounding tissue fluid and nutrients cholines B. reabsorption by a neuron a low-density lipoprotein that becomes internalized by a hepatic cell acetylcholine released from a neuron bacteria that is engulfed by a white blood cell

Acetylcholine released from a neuron

Explanation:

Exocytosis is movement of  substances out of the cells in the vesicles and Endocytosis is the intake of substances in the vesicles into cell by plasma membrane invagination. Endocytosis may be either phagocytosis (engulfing the solid particles forming vesicles called phagosomes) or Pinocytosis (engulfing of liquid particles forming vesicles called as pinosomes).The neurotransmitter acetyl choline is released by neuron through exocytosis on the stimulation.
