What is endocytosis and exocytosis?
endocytosis and exocytosis is the taking in and expelling of nutrients and waste in the body. Endocytosis means taking in and exocytosis means shoving out (haha ok I made that up). during endocytosis, the nutrient, or bacteria in the case of white blood cells, is taken in by having the cell mold around it until a vesicle is formed and the cell membrane reseals. exocytosis is when the products in the vacuole have been digested by enzymes and are now waste. the vacuole moves to the cell membrane and molds with it. returning the phospholipids to the bi-layer, and the waste to the ECF
