Why is photosynthesis an endergonic reaction? What products of light reactions of photosynthesis are used in the Calvin cycle? What are the two stages of photosynthesis? Which type of photosynthetic reaction will involve the splitting of water and the release of oxygen? What are the reactants an...
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,...
What is photosynthesis? A. A reaction that produces rust. B. A process by which plants make food. C. A reaction that only happens in our bodies. D. A chemical reaction when something burns. 相关知识点: 试题来源: 解析 B。原因:文中提到“Chemical reactions are also involved in ...
Answer to: Photosynthesis is a redox reaction. Which of the following is oxidized during the process? a. carbon dioxide b. water c. carbohydrate...
What is photosynthesis? Photosynthesis is the process used by plants, algae and somebacteriato turn sunlight into energy. The process chemically converts carbon dioxide (CO2) and water into food (sugars) andoxygen. The chemical reaction often relies on a pigment called chlorophyll, which gives ...

Which of the following is necessary for the dark - reaction in photosynthesis? A. Sunlight B. Chlorophyll C. ATP and NADPH D. Oxygen 相关知识点: 试题来源: 解析 C。解析:在光合作用的暗反应中,ATP和NADPH是必需的,它们是光反应产生并为暗反应提供能量和还原剂的物质。选项A,暗反应不需要阳光直接...
The radiation-damage-free structure of the photosystem II membrane protein complex, which oxidizes water into dioxygen in an oxygen evolving complex, has been determined by an X-ray free electron laser at a resolution of 1.95 Å; one of the substrate oxygen atoms in this reaction is now iden...
oxidized back to CO2by heterotrophic (as well as phototrophic) organisms. The energy released during theoxidationreaction is stored in the form of NADH and ATP, which are subsequently used for growth, metabolism, and reproduction. In addition, prehistoric plants and algae were largely responsible ...
Photosynthesis definition: Photosynthesis is a physio-chemical process carried out by photo-auto-lithotrophs. In simpler language, photosynthesis is the process by which green plants convert light energy into ‘chemical energy’. This energy transformation is only possible due to the presence of the mi...
