Answer:

<em>Three important energy carrier molecules in a cell are: ATP (Adenosine triphosphate, NADPH (Nicotinamide Adenosine Dinucleotide Phosphate) and FADH2. </em>

Explanation:

All the three carrier molecules play an important role in cellular respiration and photosynthesis. One NADH molecule is equal to 3 ATP molecule while 1 FADH2 molecule is equal to 2 ATP molecule.

During the active process, ATP is used as a form of energy because ATP dephosphorylates to ADP and Inorganic phosphate, Pi and release energy.
