Question

ATP is required in the transport of

(a) All molecules across a membrane
(b) Molecules through a protein channel
(c) Molecules to areas of lower concentrations
(d) Molecules to areas of higher concentrations

Answer 1

(d) Molecules to areas of higher concentrations

Step-by-step explanation:

The use of ATP to transport substances from a low concentration region to a high concentration region is called active transport because its against the concentration gradient.

And because it uses chemical energy from ATP is called active primary transport.
