Cells - Active Cell Transport Vocab

Active transport

Transport across the cell membrane that is against the concentration gradient and requires energy

ATP

Energy used in active transport

Protein pumps

Special transport proteins that allow individual molecules to travel against the concentration gradient

Phosphorylate

Attach a phosphate group onto a protein in protein pumps

Endocytosis

The process of taking material into the cell with vesicles created by the cell membrane

Vesicles

Pockets in the cell membrane that help with endocytosis

Pinocytosis

Cytosis with liquids

Phagocytosis

Cytosis with solids

Receptor-mediated endocytosis

A type of endocytosis where a pit in the cell membrane lined with receptor proteins picks up specific molecules from its surroundings and pinches shut to form a vesicle

Hypercholesterolemia

A disease where someone has very few or no cholesterol receptors, making cholesterol build up in the bloodstream and reduce blood flow

Exocytosis

The release of large amounts of material from the cell
