Final answer:
NAD, NADP, FAD, and ATP are important molecules involved in cellular energy metabolism. They act as coenzymes in oxidation-reduction reactions, and ATP is the primary energy currency of cells.
Step-by-step explanation:
Nicotinamide Adenine Dinucleotide (NAD), Nicotinamide Adenine Dinucleotide Phosphate (NADP), Flavine Adenine Dinucleotide (FAD), and Adenosine Triphosphate (ATP) are important molecules involved in cellular energy metabolism.
NAD and NADP act as coenzymes in oxidation-reduction reactions, accepting electrons and H+ ions. They are used in energy extraction from sugars and play a role in photosynthesis and anabolic reactions.
FAD is derived from vitamin B2 and its reduced form is FADH2. It is also used in energy extraction from sugars.
ATP is the primary energy currency of cells, providing energy for cellular processes through the transfer of phosphate groups.
