J the cell has no available energy it can use for any cellular processes.
help asap!!

Answer 1

Hello. I think it is H

Step-by-step explanation:

Active transport is a process of transporting small molecules against concentration gradient.

Which can use ATP or the energy of other molecules

For example in symport and antyport we have active transport but they don't use ATP
