The TP formed at the end of the Calvin cycle becomes the starting material for metabolic pathways that synthesize other organic compounds including carbohydrates, lipids, proteins, nucleic acids and chlorophyll. In the chloroplasts, ATP is a product of the first stage of photosynthesis, and it provides energy for the second stage. Describe The Role Of Chlorophyll In The Biochemical Pathways Of Photosynthesis? The light reactions of photosynthesis occur in the thylakoids and depend on the interplay of two photosystems. In NADP, the reduced form is NADH and the oxidized form is NADP +. The ATP and NADPH formed in the light-dependent stage are used as the energy and electron carriers to transfer the energy to the next stage of photosynthesis which is called the light-independent stage or the dark reaction or the Calvin Benison Cycle. Together, the ATP and the NADPH provide energy to drive the light-independent Calvin Cycle, which fixes carbon from CO 2 into organic compounds. Upon illumination, photosystem I in chloroplasts catalyzes light-driven electron transport from plastocyanin to ferredoxin, followed by the reduction of NADP + to NADPH by ferredoxin:NADP + reductase for CO 2 fixation.

Why Is Photosynthesis Considered An Energy-storing Reaction? What are the qualifications of a parliamentary candidate? NADP + functions as a carrier to transfer high energy electrons from chlorophyll to other molecules. So, this is the key difference between NAD and NADP. ATP is produced by other electron acceptors in the electron transport chain. The release of energy from the bonds of sugar, or the input of energy from the sun, allows the cells of these organisms to bind hydrogen with two electrons to NADP+, creating NADPH which can mo… During the interaction, the electrons change NADP from its oxidized state - NADP + - to its reduced state - NADPH. The role of NADPH in photosynthesis is shown in figure 2. In What Ways Do People Use The Products Of Photosynthesis In Their Everyday Lives? I Broke It On Holiday And Couldn't Get To Hospital. The role of NADP is to carry the hydrogen atom from the light dependent stage, which comes from the water molecule ( water molecule splits to form H+ , 2electrons & oxygen, which is a waste gas). Nicotinamide adenine dinucleotide phosphate, abbreviated NADP + or, in older notation, TPN (triphosphopyridine nucleotide), is a cofactor used in anabolic reactions, such as the Calvin cycle and lipid and nucleic acid syntheses, which require NADPH as a reducing agent.It is used by all forms of cellular life.
