Which is true of active transport? WILL CASHAPP AND REWARD

A. the energy used by the cell is in the form of the ADP molecule

B. Molecules called pumps function to control active transport

C. In active transport the cel does not have to do any work as nature moves the materials across the cell membrane

D. In active transport, the cell must push the molecules from a tree as of higher concentration to areas of lower concentration

I think (B) Molecule called pumps function to control active transport

Explanation:

the proteins involved are pumps that normally used chemical energy in the form of APT. These proteins have receptors that bind to specific molecules.eg:glucose. and transport across the cell membrane.these is known as active transport.

i think its c. amphipod
