Question

Quizplus · Accepted Answer

Endocytosis is a process by which cells internalize substances from the extracellular environment. It involves the formation of vesicles from the plasma membrane, which can then bring in various molecules or particles, including infectious agents such as bacteria or viruses. Once inside the cell, the vesicles fuse with lysosomes, which contain enzymes that can degrade and destroy the ingested material. Phagocytosis is a type of endocytosis that involves the uptake of large particles or cells, while pinocytosis is a type of endocytosis that involves the uptake of fluids or dissolved substances. Exocytosis is the opposite process, in which cells release substances or waste products into the extracellular space.
