Phosphorylation is a chemical process in which a phosphoryl group (PO32-) is added to an organic compound. So the correct answer here is B and this could be identified by the similarity in their names as they both have phosphor relation in their name. Expert Help. A: Photosynthesis is a process . This is the addition of a phosphate to ADP to for ATP. Q:What are the roles of NADPH and ATP in the chemical stage of photosynthesis? Energy from ATP and electrons from NADPH are used to reduce CO2 and build sugars, which are the ultimate energy storage directly arising from photosynthesis. These include Photosystem II (PS II), Cytochrome b6f complex (Cb6f), Photosystem I (PS I), and ATP synthase. Oxidative phosphorylation occurs on the inner mitochondrial membrane and the high energy electrons originate from reduced coenzymes NADH and FADH2 (from the Krebs Cycle, Link Reaction and Glycolysis), whereas non-cyclic photophosphorylation occurs on the thylakoid membrane in the chloroplasts, and the electrons Noncyclic photophosphorylation involves both Photosystem I and Photosystem II and produces ATP and NADPH. Does photophosphorylation require oxygen? In mechanism photophosphorylation is most similar to A Substrate level from BIOL 215 at Case Western Reserve University. The light reactions produce ATP and NADPH, which are used by the Calvin cycle. (c) Evolution of the many versions of the Z-Scheme: Louis Duysens and Jan Ameszs 1961 experiments on oxidation and reduction of cytochrome f by two different wavelengths of light, followed by the work of many others for more than 50 years. They absorb photons with high efficiency so that whenever a pigment in the photosynthetic reaction center absorbs a photon, an electron from the pigment is excited and transferred to another molecule almost instantaneously. Q:Differentiate the cyclic and non- cyclic photophosphorylation. ATP synthesis involves the transfer of electrons from the intermembrane space, through the inner membrane, back to the matrix. This process produces no NADPH and no O2, but it does make ATP. When the carbon dioxide concentration is increased indefinitely is photosynthesis also increased indefinitely? b. produces no ATP. 1 Cyclic and Noncyclic Photophosphorylation.
