Question

which membrane transport process consumes atp and uses a carrier?
multiple choice
osmosis
diffusion
facilitated diffusion
active
passive

Explanation:

Osmosis is the diffusion of water across a semi - permeable membrane and does not use a carrier or consume ATP. Diffusion is the movement of substances from high to low concentration without using a carrier or ATP. Facilitated diffusion uses a carrier but does not consume ATP. Active transport uses carrier proteins and requires ATP to move substances against their concentration gradient. Passive transport does not consume ATP.

Answer:

D. Active
