Endocytosis and Lysosomal Pathway

A set of vocabulary flashcards covering key concepts related to endocytosis, clathrin-coated vesicles, and the lysosomal pathway.

Endocytosis

The uptake of materials by invagination of the plasma membrane.

Clathrin-coated vesicles

Specialized vesicles that form during receptor-mediated endocytosis to transport molecules into the cell.

Phagocytosis

A type of endocytosis where cells engulf large particles or microorganisms.

Receptor-mediated endocytosis

Selective uptake of extracellular molecules by receptors in the plasma membrane.

LDL (Low Density Lipoprotein)

A type of cholesterol carrier in the bloodstream that is transported into cells via receptor-mediated endocytosis.

V-type ATPase

An enzyme that pumps protons across membranes, contributing to the acidic environment of late endosomes and lysosomes.

Dynamin

A GTPase that plays a crucial role in the fission of vesicles from membranes.

Endosomes

Membrane-bound compartments involved in transporting and processing endocytosed materials.

Multivesicular bodies

Intermediate structures in the endosomal pathway formed by the invagination of early endosomes.

Adaptin

A protein that assists in binding cargo receptors to clathrin during vesicle formation.
