NAD+

FAD
|
Detailed explanation-1: -The reduced form of NAD is designated as NADH and oxidized form as NAD+. Each form helps to carry electrons from one reaction to another. It also plays a vital role in energy production via redox reactions. Therefore, the correct answer is (a) NADH.
Detailed explanation-2: -Total ATP production Each molecule of reduced NAD produces 3 ATP and each molecule of reduced FAD produces 2 ATP. Remember that the link reaction and Krebs cycle happen twice for each molecule of glucose, because it is converted into 2x pyruvate.
Detailed explanation-3: -NAD is a coenzyme that mediates redox reactions through a transfer of electrons between NAD+ (its oxidized form) and NADH (its reduced form). Hundreds of enzymes use NAD as a coenzyme and regulate various metabolic pathways32. NGD and NHD are also believed to function as electron donors or acceptors.
Detailed explanation-4: -Inside the mitochondria, one molecule of NADH is equivalent to 3 ATP.
