When is endocytosis used? What typical cell type would be involved?

Question

Natalie Ahrens · Accepted Answer

Endocytosis is the process of taking big particle into the cell by engulfing them using a vesicle. Examples of this are the white blood cell engulfing bacteria. There is also paramecium engulfing a droplet from the pond which is full of nutrients.

undefined Endocytosis is used by cells to take in substances from the external environment by engulfing them into vesicles formed from the cell membrane. This process is utilized by various cell types, including epithelial cells, immune cells, and nerve cells, among others, for various purposes such as nutrient uptake, receptor internalization, and immune response.

undefined Endocytosis is a cellular process used by cells to internalize substances from the external environment. It occurs when the cell membrane invaginates, forming a vesicle that encloses the extracellular material. Endocytosis is used by cells for various purposes, including nutrient uptake, receptor-mediated signaling, and clearance of debris or pathogens.

One typical cell type involved in endocytosis is epithelial cells. Epithelial cells line various surfaces and cavities in the body, such as the intestines, kidneys, and blood vessels. These cells often engage in endocytosis to absorb nutrients, hormones, and other substances from the external environment for cellular functions or transport across barriers. Additionally, immune cells, such as macrophages and neutrophils, utilize endocytosis to engulf and eliminate foreign particles, pathogens, and cellular debris as part of the body's defense mechanisms.
