What is the function of NADP in photosynthesis?
1 Expert Answer. NADP+ functions as a carrier to transfer high energy electrons from chlorophyll to other molecules.
What does NADP+ and NADPH do in photosynthesis?
Photosynthesis uses a different energy carrier, NADPH, but it functions in a comparable way. The lower energy form, NADP+, picks up a high energy electron and a proton and is converted to NADPH. When NADPH gives up its electron, it is converted back to NADP+.
What is the role of NADP in photosynthesis quizlet?
What is the role of NADP+ in photosynthesis? It is reduced and then carries electrons to the Calvin cycle. As a component of photosystem II, it catalyzes the hydrolysis of water. It acts as the primary electron acceptor for the photosystems.
What is function of NADP or NADPH?
NADP+ is a coenzyme that functions as a universal electron carrier, accepting electrons and hydrogen atoms to form NADPH, or nicotinamide adenine dinucleotide phosphate. NADP+ is created in anabolic reactions, or reaction that build large molecules from small molecules.
What is the function of Rubisco in the Calvin cycle?
What is the function of rubisco during the Calvin cycle? Explanation: Rubisco is an enzyme that helps add carbon dioxide to RuBP molecules. This in turn forms an unstable inermediate compound, which immediately breaks into two 3-PGA molecules.
Why is NADP reduced to NADPH in photosynthesis?
Firstly, NADPH accepts electrons and hydrogen. Simultaneously, the special enzymes transfer these particles to the NADP+ molecule. In this reaction the NADP+ reduces when it accepts the electrons and the hydrogen, going from a positive electrical form to much negative neutral state as an NADPH molecule.
What is the role of Rubisco in photosynthesis?
The enzyme ribulose 1,5-bisphosphate carboxylase (Rubisco) catalyses the entry of carbon dioxide into photosynthetic metabolism, provides acceptor molecules that consume the products of the light reactions of photosynthesis, and regulates the pool sizes of important photosynthetic intermediates.
Why is Rubisco important in the Calvin cycle?
Transcribed image text: Rubisco is an important enzyme in the Calvin cycle. It catalyzes the addition of carbon dioxide and water to ribulose-1.5-bisphosphate, which then forms two molecules of 3-phosphoglycerate. Rubisco acts as a carboxylase and is essential for carbon fixation.
What is NADPH vs NADH?
NADH and NADPH are the reduced forms of NAD and NADP, respectively. Though NADH and NADPH are structurally more similar, they differ by their role in the cell. The main difference between NADH and NADPH is that NADH is used in cellular respiration whereas NADPH is used in photosynthesis.
