How are Large Substances Moved During Exocytosis

Question

How are large substances moved during exocytosis?
A) out of the cell
B) into the cell
C) between organelles
D) through protein channels in the plasma membrane

Accepted Answer

Exocytosis is the process by which large substances such as proteins, carbohydrates, and lipids are moved out of the cell. This process involves the packaging of these substances into vesicles that are transported to the plasma membrane of the cell. Once the vesicles come into contact with the plasma membrane, they fuse with it and release their contents outside the cell. Therefore, choice A is the correct answer.
