WebRemember, I've said multiple times, the dark reactions are badly named. They're more the light independent reactions. But they both occur simultaneously-- the light independent and light dependent-- and only during the daytime. And if your stomata is closed, you need to perform photosynthesis, especially the Calvin cycle, you need CO2. WebAs a plant's environment becomes hot, dry, and bright, its stomata, where carbon dioxide enters the leaf, tend to close. This lowers the concentration of carbon dioxide into the Calvin cycle, causing the cycle to accept oxygen in place of the carbon dioxide and makes a new product. This new product splits, and part of it is then exported out of ...

WebMay 31, 2024 · Can the Calvin cycle occur at night? Though it is called the “dark reaction”, the Calvin cycle does not actually occur in the dark or during night time. This is because the process requires reduced NADP which is short-lived and comes from the light-dependent reactions. Where do the light reactions in the Calvin cycle take place? … WebThe reactions of the Calvin cycle are not directly dependent on light, but they usually do not occur at night. Why? It is often too cold at night for these reactions to take place. … WebThere are two important adaptations that allow C4 plants to do this: First, C4 plants use an alternate enzyme for the first step of carbon fixation. This enzyme is called phosphoenolpyruvate (PEP) carboxylase, and it has no oxygenase activity and has a much higher affinity for CO2 than rubisco. As the name “PEP carboxylase” suggests, the ... buckland computers
