Question

which form of transport is being shown in the diagram. osmosis diffusion active transport facilitated diffusion

Explanation:

• Osmosis is the movement of water molecules across a semi - permeable membrane. This diagram is not about water, so osmosis is incorrect.
• Diffusion is the movement of molecules from an area of high concentration to an area of low concentration without the help of a protein. In the diagram, there is a protein involved, so diffusion is incorrect.
• Active transport moves molecules against the concentration gradient (from low to high) and requires energy. The diagram shows movement down the concentration gradient (from high to low on the right side), so active transport is incorrect.
• Facilitated diffusion is the movement of molecules down the concentration gradient (from high to low) with the help of a protein channel. This matches the diagram.

Answer:

facilitated diffusion
