What is osmosis?

Back

The movement of water across a semipermeable membrane from low solute concentration to high solute concentration.

Front

What is facilitated diffusion?

Back

The process of transporting molecules across a cell membrane via protein channels without energy.

Front

What is active transport?

Back

The movement of molecules against their concentration gradient, requiring energy (ATP).

Front

What role do carrier proteins play in cell transport?

Back

They assist in the movement of substances across the cell membrane.

Front

What is the difference between endocytosis and exocytosis?

Back

Endocytosis is the process of taking substances into the cell, while exocytosis is the process of expelling substances from the cell.
