How is energy expended in active transport?

a. glycolysis
b. lysic acid
c. atp
d. krebs cycle

The correct answer is ATP.

Explanation:

When molecules or ions moves into higher concentration from lower concentration through a cell membrane with the help of enzymes and requires energy, this type of transport of molecules or substances called active transport. Active transport requires chemical energy to perform this transport and ATP is the form of chemical energy expended in this process. ATP is an abrevation of adenosine triphosphate.
