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,...
NADPH in Biology | Definition, Structure & Function from Chapter 17/ Lesson 16 68K 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. ...
相关知识点: 试题来源: 解析 B。解析:“In the light-dependent reactions, light energy is absorbed by chlorophyll and converted into chemical energy in the form of ATP and NADPH.”说明叶绿素在光合作用中的作用是吸收光能并将其转化为化学能。反馈 收藏 ...
nergy F. rom ATP to NADPH in the light - reaction 相关知识点: 试题来源: 解析 C。解析:在光合作用中,酶Rubisco的功能是催化暗反应中二氧化碳的固定。选项A,在光反应中,帮助分解水的不是Rubisco。选项B,Rubisco不参与光反应中氧气的产生。选项D,Rubisco不参与光反应中ATP向NADPH的能量转移。
Briefly explain the role of NADPH in photosynthesis. What are the uses of ATP? What do we use ATP for? What is teh role of NAD+ and NADH in cellular respiration? Describe the role of ATP and NADPH in the Calvin cycle. What is the function of sunlight in photosynthesis?
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...
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,...
(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 ...
