Cell Transport

Front

Explain the function of the plasma membrane using the diagram.

Back

The plasma membrane maintains homeostasis by controlling substances that enter and leave the cell.

Front

Select the answer that BEST explains the diagram.

Options: Simple Diffusion. Molecules are moving from a high concentration to a low concentration through a protein. Facilitated Diffusion. Molecules are moving from low concentration to a high concentration through a protein. Simple Diffusion. Molecules are moving from a low concentration to a high concentration through a protein. Facilitated Diffusion. Molecules are moving from a high concentration to a low concentration through a protein.

Back

Facilitated Diffusion. Molecules are moving from a high concentration to a low concentration through a protein.

Front

Back

Exocytosis; Active

Front

Osmosis is diffusion of water. Select the BEST answer choice: Molecules move down the concentration gradient through the phospholipids, Molecules move up the concentration gradient through proteins, Molecules move up the concentration gradient through the phospholipids, Molecules move up the concentration gradient through proteins.

Back
