Question

which part of the cell membrane is responsible for transporting ions, molecules that go against the concentration gradient, or ones that cannot diffuse through? select two correct answer(s).

Explanation:

Integral membrane proteins and carrier - proteins are responsible for active transport (against the concentration gradient) and transporting molecules that cannot diffuse through the lipid - bilayer of the cell membrane. In the diagram, structures like transporters (which could be channel - proteins or carrier - proteins) are integral membrane proteins.

Answer:

1. Integral membrane protein; 6. Carrier - protein
