What does light reaction use and produce? Chloroplasts /ˈklɔːrəˌplæsts plɑːsts/ are organelles specialized subunits in plant and algal cells. Their discovery inside plant cells is usually credited to Julius von Sachs (1832–1897) an influential botanist and author of standard botanical textbooks – sometimes called "The Father of Plant Physiology". Nicotinamide adenine dinucleotide phosphate abbreviated NADP⁺ or in older notation TPN 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. Adenosine triphosphate is a complex organic chemical that provides energy to drive many processes in living cells e.g. muscle contraction nerve impulse propagation and chemical synthesis. Found in all forms of life ATP is often referred to as the "molecular unit of currency" of intracellular energy transfer. Wh… What does the light dependent reaction of photosynthesis ... Photosynthesis Review Answers - The Biology Corner What are byproducts of photosynthesis? - Quora Light/Dark Reactions - Process of Photosynthesis Thu Jun 17 2010 · The light dependent reaction produces two useful substances for the plant: ATP and NADPH. In addition it produces a waste product oxygen gas . The ATP and the NADPH are then used in the light independent reaction. The oxygen is released into the atmosphere. The reaction center is in the thylakoid membrane. It transfers light energy to a dimer of chlorophyll pigment molecules near the periplasmic (or thylakoid lumen) side of the membrane. This dimer is called a special pair because of its fundamental role in photosynthesis. This special pair is slightly different in PSI and PSII reaction center. In PSII it absorbs photons with a wavelength of 680 nm and it is therefore called P680. In PSI it absorbs photons at 700 nm and ...
