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

Answer 1

Answer:

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.
