What is the function of NAD and FAD in photosynthesis and cellular respiration?

∙ 12y ago
Cellular respiration is a group of reactions that break down glucose, fatty acids, and amino acids in the cell. FAD and NAD+ function as reversible hydrogen acceptors that deliver the accepted hydrogen to the electron transport chain.

∙ 14y agoNAD and FAD become NADH and FADH2 respectively, this is because they become electron carriers. This happens in the breakdown of Acetyl CoA in the Krebs Cycle (aka the citric acid cycle) inside the second membrane of the mitochondria. NADH and FADH2 will carry and donate the electrons to the Electron Transport Chain on the internal membrane; the transfer of the electron's energy allows for the proteins crossing the membrane to pump hydrogen ions into the space between the two membranes and build up a gradient for chemiosmosis. The NADH and FADH2 becomes NAD and FAD again and returns to the Krebs cycle.

What factors affect the rate of cellular respiration?
The availability of the reactants needed for respiration (CO2, ADP, NAD+, FAD, H+, etc). The reactants are formed by photosynthesis.
Electrons are brought to the electron transport by what high energy electron carriers?
NADP if photosynthesis. NAD or FAD if cellular respiration.
What molecules serve as intermediate electron carriers in the process of cellular respiration?
They can accept electrons and transfer mos of their energy to another Molecule.
What are two examples of coenzymes used in cellular respiration?
Acetyl-CoA: CoA=Co-enzyme A; Coenzyme I, coenzyme II, coenzyme A and B-12 and coenzyme Q.
What is NAD and FAD?
NAD stands for nicotinamide adenine dinucleotide and FAD stands for flavin adenine dinucleotide. Both are electron carriers which have many roles to perform.

What hydrogen carriers are used in cellular respiration?
NAD and FAD are the two hydrogen carriers involved in respiration. NAD is reduced in glycolysis, the Link Reaction and the Krebs Cycle to NADH + H+; whilst FAD is reduced to FADH2 solely in the Krebs Cycle. The role of the hydrogen carriers is to transport the hydrogen atoms to the Electron Transport Chain, where their energy is used to join ADP and Pi to give a molecule of ATP.
What terminal electron acceptors are used in anaerobic cellular respiration?
anaerobic cellular respiration has 3 different stages, and their final electron acceptors are: pyruvate oxidation- NAD+ Krebs cycle- NAD+, FAD+ electron transport chain- Oxygen
What are two examples of coenzymes used in cellular respiration?
Acetyl-CoA: CoA=Co-enzyme A; Coenzyme I, coenzyme II, coenzyme A and B-12 and coenzyme Q.
Energy released from glucose by cellular respiration - that is transported to all areas of the Cell - is in the form of what?
The nucleotide Adenosine tri-phosphate, primarily. Also involved are FAD-H and NADP-H.
What is NAD and FAD?
NAD stands for nicotinamide adenine dinucleotide and FAD stands for flavin adenine dinucleotide. Both are electron carriers which have many roles to perform.
What are NAD and FAD?
Electron acceptor that carry electrons by becoming reduced from oxidized products of respiration/photosynthesis and carry these electrons to the mitochondria.
What acts as an electron carrier in cellular respiration?
NADH, but it looks like NAD+. The plus means H though. N means nicotinamide. A means adenine. And D means dinucleotide. It's kind of confusing but with my help you should understand it. I hope i helped!:-)
What molecules are needed for cellular respiration?
Cellular Respiration is a complex process which uses many different molecules, such as Oxygen, Water, ATP, NAD, NADH, FAD, FADH, Acetyl CoA, and others. If you are asking about the fuel consumed in Cellular Respiration, that would primarily be Glucose.
What are three hydrogen carriers involved in aerobic respiration?
Nad, nadp, fad
