Question

Quizplus · Accepted Answer

Receptor-mediated endocytosis imports target molecules by utilizing specific membrane proteins, which bind to the target molecules before they are internalized into the cell. This process requires energy from the cell in the form of ATP. Therefore, options A, C, D, and E are incorrect.
