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 ...
相关知识点: 试题来源: 解析 B。中文解析:文章中提到 In the process of photosynthesis in plants is a redox reaction. Carbon dioxide is reduced to form glucose.(植物的光合作用过程是一个氧化还原反应。二氧化碳被还原形成葡萄糖。)所以选 B。 反馈 收藏 ...
Photosynthesis is the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxyg
During the dark - reaction stage of photosynthesis, which substance is fixed? A. Oxygen B. Water C. Carbon dioxide D. Glucose 相关知识点: 试题来源: 解析 C。解析:在光合作用的暗反应阶段,二氧化碳被固定。选项A,氧气是光反应的产物,不是暗反应固定的物质。选项B,水是在光反应阶段被利用的。选项D...
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...
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 ...
Answer to: Photosynthesis is a biochemical reaction that converts oxygen and carbohydrates to carbon dioxide and water. (a) True (b) False. By...
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...
The impact of pufLM gene sequences for studies on the environmental diversity of phototrophic bacteria is discussed and the possibility of their identification on the species level in environmental samples is pointed out. 展开 关键词: photosynthetic reaction center proteins Proteobacteria phototrophic ...
