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,...
The transition from anaerobic to aerobic photosynthesis 2.7 billion years ago was accompanied by profound changes on the acceptor side of the ancestral Type I reaction center. At the advent of oxygen evolution, the mobile bacterial dicluster ferredoxin, which initially served to transfer electrons ...
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 photosystem I reaction center in oxygenic photosynthesis In the photosynthetic apparatus of green plants, two types of reaction centers named Photosystem-I and Photosystem-II (PS-I, PS-II) work in series to transfer electrons from water to NADP+ (see Chapter 5). This endergonic reaction is...
Light energy is used to make this “uphill” reaction possible. Photosynthesis is a complex, multistage process. Its main parts are (1) the primary photochemical process in which light energy absorbed by chlorophyll is converted into chemical energy, in the form of some energy-rich intermediate ...
The input reaction in photosynthesis or the light-dependent reaction is considered the first part of photosynthesis. It starts in the process where the leaves absorb light energy by pigments, which is needed for the process. These pigments are then converted into chemical energy such as NADPH an...
2.Four-step model in an artificial photosynthetic reaction Photosynthesis is the process by which plants,algae and some bacteria use light energy to split water and to use the electrons and hydrogen ions produced for the reduction of carbon dioxide to sugar. Photosynthesis can be divided into two...
Pachypodol acts as a Hill reaction inhibitor with its target on the water splitting enzyme located in PSII. In the search for new herbicides from natural compounds, flavonoids 1 and 2 and flavonoid analogues quercetin (3), apigenin (4), genistein (5), and eupatorin (6) were assessed for ...
What is the importance of the light and dark reactions in photosynthesis? For what purpose does a plant use the sugars produced during photosynthesis? What starts the light reaction of photosynthesis? What is the role of turgidity in photosynthesis? What is water's role in the light rea...
Fong,FrancisK - Light reaction path of photosynthesis 被引量: 89发表: 1982年 Photosynthesis-The Light Reactions During the past three or four years there has been a substantial advance in our knowledge of the light reactions in photosynthesis. This comes at a time of... K Sauer - 《Annual...
