Practice: Membrane Transport 3

You are running an experiment in the lab to determine if your bacterial cells take up lactose using active transport, facilitated diffusion, or both. You add an ATP inhibitor to the culture and measure the ratio of lactose inside the cell vs. outside the cell over time. Based on the graph below, which type of transport is used by the cells?

ATP-dependent active transport

Facilitated diffusion

Both A and B

None of the above
