- Best Answer: Nicotinamide adenine dinucleotide phosphate (NADP) A phosphorylated derivative of NAD which functions as a coenzyme and is reduced to NADPH.In chloroplasts, NADP is reduced by ferredoxin-NADP+ reductase in last step of the electron chain of the light reactions of photosynthesis.The NADPH produced is then used as reducing power for the biosynthetic reactions in the Calvin cycle of photosynthesis.n chloroplasts, NADP is reduced by ferredoxin-NADP+ reductase in last step of the electron chain of the light reactions of photosynthesis.

Nicotinamide adenine dinucleotide Nicotinamide adenine dinucleotide (NAD) is a coenzyme found in all living cells. The compound is a dinucleotide, because it consists of two nucleotides joined through their phosphate groups. One nucleotide contains an adenine base and the other nicotinamide.Nicotinamide adenine dinucleotide exists in two forms, an oxidized and reduced form abbreviated as NAD+ and NADH respectively.icotinamide adenine dinucleotide, like all dinucleotide s, consists of two nucleotides joined by a pair of bridging phosphate groups. The nucleotides consist of ribose rings, one with adenine attached to the first carbon atom (the 1' position) and the other with nicotinamide at this position.

What Is Nadph in Photosynthesis? NADPH. During the Light Dependent Cycle of photosynthesis, light is absorbed by the chlorophyll. The electrons are excited, which starts them moving from one enzyme to another. A hydrogen atom attaches itself to an NADP molecule, converting it to NADPH.uring the Light Dependent Cycle of photosynthesis, light is absorbed by the chlorophyll.

- NADH, short for nicotinamide adenine dinucleotide, is an important pyridine nucleotide that functions as an oxidative cofactor in eukaryotic cells.NADH plays a key role in the production of energy through redox reactions.icotinamide adenine dinucleotide (NAD) is one of the most important coenzymes in the cell. Not surprisingly, NAD and the closely related NADP are the two most abundant cofactors in eukaryotic cell.

- NADH is the abbreviation used for Nicotinamide Adenine Dinucleotide, one of the most important coenzymes in the human brain and body. A coenzyme is the active, or working form of a vitamin. NADH is the reduced (electron-energy rich) coenzyme form of vitamin B3, while NAD is the oxidized (burned) coenzyme form of B3.NAD and NADH are converted into each other in numerous different metabolic activities.t is vitamin B3 (niacinamide) combined with a ribose (5-carbon sugar), a phosphate group and an adenine nucleotide (a DNA component). NAD(H) can be made in the liver and other cells from vitamin B3. It can also be made from the amino acid L-Tryptophan at the expensive ratio of 60mg tryptophan for 1mg B3.

Energy for Life NADH+ is the same molecule as NADPH but is a low energy molecule, In order to become NADPH it must gain 1 Hydrogen atoms (proton) and 2 electrons. When a substance gains electrons it is said to be reduced. Therefore, NADP+ is reduced to become NADPH. The NADPH is used in cells for energy.

Nicotinamide adenine dinucleotide phosphate Nicotinamide adenine dinucleotide phosphate, abbreviated NADP+ or, in older notation, TPN (triphosphopyridine nucleotide), is a cofactor used in anabolic reactions, such as lipid and nucleic acid synthesis, which require NADPH as a reducing agent.NADPH is the reduced form of NADP + .n plants [edit]. In photosynthetic organisms, NADPH is produced by ferredoxin-NADP+ reductase in the last step of the electron chain of the light reactions of photosynthesis.

FADH2 & NADH: Definition & Overview FADH2 and NADH Defined. Flavin adenine dinucleotide, or FADH2, is a redox cofactor that is created during the Krebs cycle and utilized during the last part of respiration (the electron transport chain).Nicotinamide adenine dinucleotide, or NADH, is a similar compound and used more actively in the electron transport chain as well.In fact, more NADH is produced and used than FADH2 in the process of creating energy. There are actually 6 NADH produced and only 2 FADH2 molecules.ADH2 and NADH are created from FAD and NAD+ through redox (reduction-oxidation) reactions in the Krebs cycle during respiration as seen below here: This cycle gives off small amounts of energy in the form of ATP (adenonsine triphosphate, cell energy) and produces these compounds, FADH2 and NADH.

NADH vs. NADPH: Where is each one used and why that instead of the other? NADPH is primarily produced in the oxidative part of the pentose phosphate pathway. NADPH is used in a) anabolic syntheses to produce cholesterol, fatty acids, transmittor substances and nucleotides. b) detoxifying processes as an antioxidant.ADPH is primarily produced in the oxidative part of the pentose phosphate pathway.

Meaning of NADH in biology? In metabolism, nicotinamide adenine dinucleotide is involved in redox reactions, carrying electrons from one reaction to another. The coenzyme is, therefore, found in two forms in cells: NAD+ is an oxidizing agent – it accepts electrons from other molecules and becomes reduced. This reaction forms NADH, which can then be used as a reducing agent to donate electrons. These electron transfer reactions are the main function of NAD.
