Which the following descriptions would be an example of exocytosis? Which the following descriptions would be an example of exoc
ytosis? 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
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.
Lysosome are among the organelles in a eukaryotic cell. Lysosomes are formed by the golgi bodies or the golgi apparatus.
<em><u>The role of lysosomes is to digest and destroy old and worn out organelles together with cellular wastes. In other words Lysosomes break down food molecules, waste products, and old worn out cells or organelles.</u></em>
They contain powerful lytic enzymes and and acids which help in the digestion and recycling of cellular materials.
