Question

multiple choice 1 point
when solutes move against the concentration gradient using a protein pump
active transport
passive transport
facilitated diffusion
osmosis

Explanation:

Active transport is the process where solutes move against the concentration gradient. This requires energy (usually in the form of ATP) and often uses protein pumps. Osmosis is the movement of water across a semi - permeable membrane. Facilitated diffusion and passive transport involve the movement of substances down the concentration gradient (from high to low concentration) without the need for energy input (in the case of passive transport) or with the help of transport proteins (in facilitated diffusion) but still following the concentration gradient.

Answer:

Active Transport
