Calvin Cycle Definition. As per the definition, Calvin cycle is a set of reactions taking place in the dark reaction of the photosynthesis, which means that it does not require sunlight. The Calvin cycle can be divided into two stages. The light-independent Calvin cycle, also (misleadingly) known as the "dark reaction" or "dark stage," uses the energy from short-lived electronically-excited carriers to convert carbon dioxide and water into organic compounds[2]that can be used by the organism (and by animals that feed on it). The Calvin cycle requires _____ and _____ from the light reactions in order to operate. This set of reactions is also called carbon fixation. Also, if poison bounded and inhibited the ATP synthase then I believe that the Calvin cycle would not receive ATP which would stop the cycle. • ATP is the energy source, while NADPH is the reducing agent that adds high-energy electrons to form sugar. A. 120 seconds . This is catalysed by rubisco. The Calvin cycle, which takes place in the stroma, uses energy derived from these compounds to make GA3P from CO2. If a classmate asserted that the light reactions don't depend on the Calvin cycle, could just keep on producing ATP and NADPH, how would you respond? • ATP is the energy source, while NADPH is the reducing agent that adds high-energy electrons to form sugar. This cycle was first formed by Melvin Calvin. The Calvin cycle (or Calvin-Benson cycle or carbon fixation) is a series of biochemical reactions that takes place in the stroma of chloroplasts in photosynthetic organisms. If you are on a personal connection, like at home, you can run an anti-virus scan on your device to make sure it is not infected with malware. Input CO2 ATP NADPH (converts CO2 to sugar … These reactions actually have several names associated with them. O2. Occurrence of Dark Reaction. This phase requires sunlight to fix carbon dioxide. And so we're going to talk about the autotrophs. This process of “carbon fixation” is how most new organic matter is created. Which of the following statements is true about the Calvin cycle? • The Calvin cycle uses ATP and NADPH from the light reaction to form sugars.
