Tell us a little about yourself to get started. NADPH is an energy-carrying molecule created during the first part of photosynthesis when chloroplasts convert light energy into chemical energy. This is typically done during photosynthesis in plants, or as part of sugar digestion in animals. Applications and skills: NADPH is the reduced form of the electron acceptor NADP+. NADPH is the reduces from of NADP (Nicotinamide Adenine Dinucleotide Phosphate) which is a hydrogen carrier molecule. ADP + NADP + H2O → ATP +NADPH + H ion + O2 The reason why this stage is called “Light Reaction” is because light plays a big part of the reaction, enzymes are also required to catalyse them. In the chloroplasts, ATP is a product of the first stage of photosynthesis, and it provides energy for the second stage. NADPH is an electron carrier. In the cell, NADP is the electron acceptor which is reduced in the light-dependent reactions, and which provides electrons and hydrogen for the light-independent reactions. In oxygenic photosynthesis, the first electron donor is water, creating oxygen as a waste product. Photosynthesis Light Reaction. PHOTOSYNTHESIS- Light dependent reaction.

Such a reaction usually starts with NAD from either the de-novo or the salvage pathway, with NAD kinase adding the extra phosphate group. Is it by the protons from the photolysis of water? Glycerate 3-phosphate is reduced to triose phosphate using reduced NADP and ATP. Cytochrome b6f and ATP synthase work together to create ATP. Under the conditions existing in a normal cell, the hydrogen atoms shown in red are dissociated from these acidic substances. why do people remarry/redate after their partner dies? In photosynthesis, the light-dependent reactions take place on the thylakoid membranes.The inside of the thylakoid membrane is called the lumen, and outside the thylakoid membrane is the stroma, where the light-independent reactions take place.The thylakoid membrane contains some integral membrane protein complexes that catalyze the light reactions.
