No, photosynthesis does not happen at night because the light reactions, which are necessary to produce ATP and NADPH for the dark reactions, cannot occur without sunlight. 光合作用需要光能,主要发生在白天。光反应需要阳光才能进行,产生ATP和NADPH,为暗反应提供能量。夜间没有阳光,光反应无法进行,因此光合...
Describe how the light reactions of photosynthesis produce ATP and NADPH. What are the structural and functional differences between NADH and NADPH? Describe the role of ATP and NADPH in the Calvin cycle. How are ATP, ADP, NADP+, and NADPH cycled in photosynthesis?
Question: What does chemiosmosis produce? Osmosis: Osmosis is the movement of a solvent across a semi-permeable membrane. It is a passive process which is used by living organisms to maintain water balance. Answer and Explanation:1 Chemiosmosis produces ATP. It is the process by which ions or...
During the first stage of photosynthesis, the light-dependent reactions, chlorophyll absorbs energy from sunlight. Water is split with this energy from the sun, which produces oxygen, adenosine triphosphate (ATP) and nicotinamide adenine dinucleotide phosphate hydrogen (NADPH). The second stage of phot...
What does the Krebs cycle produce?Krebs cycleThe Krebs cycle, or TCA cycle is a chemical pathway that releases chemical potential energy from macromolecules such as carbohydrates and lipids and turns them into ATP via oxidative phosphorylation or the electron transport chain. This pathway produces ...
The Calvin cycle refers to the light-independent reactions in photosynthesis that take place in three key steps. Although the Calvin Cycle is not directly dependent on light,it is indirectly dependent on lightsince the necessary energy carriers ( ATP and NADPH) are products of light-dependent reac...
green fluorescent protein (GFP), followed by fluorescence microscopy. Furthermore, we compared the results to known pathways and locations of enzymes in higher plants performing C3 or C4 photosynthesis. This approach revealed that the intracellular distribution of the investigated enzymes is quite ...
What is the role of ATP in photosynthesis? ATP synthase exploits a proton gradient to produce ATP. How is the proton gradient established? A. Water is hydrolyzed to oxygen and protons in the electron transport chain B. Energy released by the oxidation of NADH and FADH2 causes protons to diff...
Electron transport chains are important in ATP production during both cellular respiration and photosynthesis. In prokaryotes, both the photosynthetic and respiratory electron transport chains are found in the cell membranes of the prokaryotes that can carry out these processes...
In photosynthesis what is the role of the electron transport chain? Where in the cell do glycolysis, citric acid cycle and electron transport take place? What is chemiosmosis and how does the H gradient help produce ATP? What happens in the electron transport chain and what ...
