Receptor-Mediated Endocytosis
Captions available
The idea
Receptor-mediated endocytosis uses a specific receptor to bind one substance before the membrane folds inward and brings it into the cell.
In practice
Cells clear LDL cholesterol through receptor-mediated endocytosis; a defective LDL receptor lets cholesterol build to dangerous blood levels.
Where people slip
A missing or defective receptor blocks this pathway — the substance stays in circulation rather than entering the cell.
