Question

Which of the following forms of transport uses ATP directly

A.facilitated diffusion
B.Active transport
C.Simple diffusion
D.Osmosis

Answer 1

Active transport is the form of transport that directly uses ATP, as it involves moving substances against their concentration gradient and requires energy.

Step-by-step explanation:

The form of transport that uses ATP directly is Active transport. Active transport involves moving substances across the cell membrane against their concentration gradient, from an area of lower concentration to an area of higher concentration. This process requires energy because it is going against the natural direction of diffusion, and this energy is typically supplied in the form of ATP. Cells use protein pumps or engage in processes like endocytosis to perform active transport, both of which are ATP-dependent.
