Final answer:
Carrier-mediated membrane transport involves active transport, passive diffusion, facilitated diffusion, co-transport, and endocytosis. These methods allow substances to move across the cell membrane using carrier proteins.
Step-by-step explanation:
There are several methods of carrier-mediated membrane transport. Active transport refers to the movement of a substance across a cell membrane from an area of lower concentration to an area of higher concentration, using cellular energy (ATP).
Passive diffusion involves the movement of substances from an area of higher concentration to an area of lower concentration, while facilitated diffusion uses carrier proteins in the cell membrane to move substances from higher to lower concentration. Other methods include co-transport, where the movement of one molecule powers the movement of another, and endocytosis, which involves the cell membrane engulfing material.
