What is exocytosis? A. The process by which a cell engulfs a large particle or another cell, eating it B. The process by which a cell expels the contents of an internal vesicle to the extracellular fluid C. The process by which a cell takes in a small amount of extracellular fluid and its contents by the ballooning inward of the plasma membrane D. Pressure that a fluid exerts against a structure that contains it

Which statement does NOT describe the actions of the Golgi apparatus? 1. The sacs comprising the Golgi are not interconnected. 2. The Golgi apparatus receives and modifies substances manufactured by the Endoplasmic reticulum. 3. The vesicles that bud off from the rough endoplasmic reticulum and enter the Golgi apparatus contain proteins, fats, or carbohydrates) 4. Products packaged from the Golgi apparatus are released into new transport vesicles that may be exported from the cell.
Imagine a cell can perform exocytosis, but only minimalendocytosis. What would happen to the cell?a. The cell would secrete all its intracellular proteins.b. The plasma membrane would increase in size overtime.c. The cell would stop expressing integral receptorproteins in its plasma membrane.d. The cell would lyse.
