Question

Quizplus · Accepted Answer

Glucose transport mechanism involves the movement of glucose molecules across the cell membrane with the help of carrier proteins, which is a type of facilitated diffusion. Simple diffusion involves the movement of molecules from an area of high concentration to an area of low concentration without the aid of a protein. Osmosis is the movement of water molecules from an area of high water concentration to an area of low water concentration. Active transport involves the movement of molecules against the concentration gradient with the aid of energy. Bulk flow involves the movement of molecules in response to a pressure gradient.
