10 Terms

1

Endocytosis

A cellular process in which substances are brought into the cell by engulfing them in a membrane.

New cards
2

Phagocytosis

The uptake of large particles, such as bacteria and apoptotic cells, by immune cells.

New cards
3

Macropinocytosis

A non-selective endocytic process where cells form actin-driven ruffles that can engulf extracellular material.

New cards
4

Opsonization

The process by which pathogens are coated with antibodies to enhance phagocytosis.

New cards
5

Clathrin-mediated endocytosis

A form of endocytosis involving vesicles coated with clathrin, aiding in the uptake of specific molecules.

New cards
6

Familial hypercholesterolemia

A genetic disorder characterized by high cholesterol levels due to mutations affecting LDL uptake.

New cards
7

Dynamin

A GTPase enzyme that is required to pinch off clathrin-coated vesicles during endocytosis.

New cards
8

Multi vesicular bodies

Late endosomes that contain many intraluminal vesicles, involved in the endocytic pathway.

New cards
9

Lysosome

An organelle containing enzymes that break down waste materials and cellular debris; has a pH of around 4.5.

New cards
10

Gradient of pH

The varying pH levels throughout the endocytic pathway, crucial for the function of endosomal maturation.
