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.

where in your body is there an enzyme that does function at a high or low ph? what is the name of that enzyme and its function?

imagine a line passing through the center of earth that goes through both the north pole and the south pole. this imaginary line is called an axis. earth spins around its axis, just as a top spins around its spindle. this spinning movement is called earth's rotation. at the same time that the earth spins on its axis, it also orbits, or revolves around the sun. this movement is called revolution.
