Question

What is endocytosis and exocytosis

Answer 1

endocytosis is the movement of any necessary substance inside the cell where as it is outside the cell in case of exocytosis

Answer 2

Answer:

• Endocytosis is the process of capturing a substance or particle from outside the cell by engulfing it with the cell membrane. The membrane folds over the substance and it becomes completely enclosed by the membrane. At this point a membrane-bound sac, or vesicle, pinches off and moves the substance into the cytosol.
• Exocytosis describes the process of vesicles fusing with the plasma membrane and releasing their contents to the outside of the cell . Exocytosis occurs when a cell produces substances for export, such as a protein, or when the cell is getting rid of a waste product or a toxin. Newly made membrane proteins and membrane lipids are moved on top the plasma membrane by exocytosis.
