Question

the diagram illustrates the movement of molecules through a cell membrane. what process is being used by the cell to move the molecules? carrier protein active transport endocytosis osmosis facilitated diffusion

Explanation:

• Active transport: Requires energy (ATP) to move molecules against their concentration gradient. The diagram does not show energy input.
• Endocytosis: Involves the cell membrane engulfing large particles or fluids to form vesicles. This is not depicted in the diagram.
• Osmosis: Specifically refers to the movement of water molecules across a semi - permeable membrane. The diagram shows a general molecule (not just water).
• Facilitated diffusion: Uses carrier proteins to move molecules (such as polar or large molecules) down their concentration gradient (from high to low concentration). The diagram shows a molecule moving through a carrier protein, which is characteristic of facilitated diffusion.

Answer:

Facilitated Diffusion
