NADPH is an energy-carrying molecule produced in the first stage of photosynthesis. It provides energy to fuel the Calvin cycle in the second stage of photosynthesis. Light-Dependent Reactions The reactions in the first stage of photosynthesisrequire lightin order to proceed. The main objective of ...
In the process of photosynthesis, what is the first product in the light - reaction? A. Glucose B. Oxygen C. ATP D. NADPH 相关知识点: 试题来源: 解析 C。解析:在光合作用的光反应过程中,第一个产生的产物是ATP。光反应中光能被叶绿素吸收后,首先用于合成ATP,然后才产生NADPH和氧气等。选项A,...
Photosynthesis:Photosynthesis is the major biochemical pathway by which energy enters ecosystem. It converts light energy from the sun into chemical energy which can be used by living organisms.Answer and Explanation: NADP+ serves as an electron carrier during photosynthesis. During photosynthesis ...
NADPH in Biology | Definition, Structure & Function from Chapter 17 / Lesson 16 69K Understand the meaning of NADPH by learning NADPH definition. Get to know more about NADPH structure, its function, and the role of NADPH in photosynthesis. Related...
NADPH is found in the cytosol as this is the site of anabolic pathways, or the reactions that use energy and lead to the creation of large molecules. NADPH plays an important role in plants during photosynthesis. It is also required to form antioxidants and for the synthesis of fatty acids...
这个NADPH+H离子则在暗反应里面充当还原剂的作用。 意义：1：光解水，产生氧气。 2：将光能转变成化学能，产生ATP，为暗反应提供能量。 3：利用水光解的产物氢离子，合成NADPH+H离子，为暗反应提供还原剂。 （5）暗反应 实质是一系列的酶促反应 条件：无光也可，暗反应酶 场所：叶绿体基质 影响...
NADPH is produced within the chemical reaction of photosynthesis and is used within the Calvin cycle to assimilate $C{{O}_{2}}$ Complete answer:NAD, is altogether living cells, where it functions as a coenzyme. It exists either in an oxidized form $NA{{D}^{+}}$, which can accept an...
(adenosine triphosphate, a source of chemical energy for cells) and NADPH — both of which are required in the next stage of photosynthesis in the Calvin cycle. The "electron hole" in the original chlorophyll pigment is filled by taking an electron from water. This splitting of water ...
This stage takes place in the thylakoid membranes of chloroplasts. Light energy, usually from the sun, is absorbed by pigments like chlorophyll, which triggers a series of reactions. These reactions produce ATP (adenosine triphosphate) and NADPH, two energy-carrying molecules, as well as oxygen,...
2 H2O + 2 NADP++ 3 ADP + 3 Pi+ light → 2 NADPH + 2 H++ 3 ATP + O2 In the dark stage, ATP and NADPH ultimately reduce carbon dioxide and other molecules. Carbon dioxide from the air is "fixed" into a biologically usable form, glucose. In plants, algae, and cyanobacteria, the...
