Which of the following statements regarding endocytosis and exocytosis is correct?

Question

Quizplus · Accepted Answer

Endocytosis is a process by which a cell takes in substances by forming vesicles from its plasma membrane. This process is used to bring large molecules, such as proteins and lipids, into the cell. Exocytosis is a process by which a cell releases substances from vesicles inside the cell to the outside of the cell by fusing the vesicles with the plasma membrane. This process is used to secrete molecules, such as hormones or neurotransmitters, out of the cell. Therefore, both choices A and B are correct. Pinocytosis and phagocytosis are both forms of endocytosis, and they involve the uptake of fluids or large particles, respectively. Neither of these processes has anything to do with exocytosis, making choice C incorrect. Therefore, the best choice is D, which accurately describes the processes of endocytosis and exocytosis.
