It cannot occur in the dark. It contains an enzyme called rubisco which is a light-activated enzyme. Also the Calvin cycle uses the chemical energy produced in the light reactions, and the light reactions need sunlight energy in order to produce the energy needed in the Calvin cycle. Hope that helps :)

Do the of photosynthesis ocdark reactions cur only at night?
No, the dark reactions of photosynthesis (Calvin cycle) can occur during the day as well. These reactions do not require light directly, but they depend on the products of the light reactions to proceed. The dark reactions convert CO2 into glucose using ATP and NADPH generated during the light reactions.
Why is the Calvin cycle sometimes called the dark reactions?
Photosynthesis, mainly the dark reactions which are responsible for the direct production of the product, is a reaction pathway that builds up a complex molecule from smaller molecules, so it is an anabolic pathway. When catabolic means breaking down {repeat: what does a cat do to your furniture} then anabolic means building up.
The dark reactions of photosynthesis are those that?
The dark reactions of photosynthesis, also known as the Calvin cycle, occur in the stroma of the chloroplast and do not require light energy. They involve the conversion of carbon dioxide into glucose through a series of enzymatic reactions. The dark reactions use the products of the light reactions, ATP and NADPH, as sources of energy and reducing power.
True or false The light reactions of photosynthesis can occur only under light conditions and the dark reactions can occur only during the dark hours?
False. The light reactions of photosynthesis require light to convert solar energy into chemical energy, while the dark reactions (Calvin cycle) do not directly rely on light and can occur in both light and dark conditions. However, the dark reactions are indirectly dependent on the products of the light reactions.
Why doesn't Calvin cycle occur at night?
Obviously, there is no sunlight energy for light dependent reactions to occur while calvin cycle AKA light independent phase does not require light as it uses energy in the form of ATP and the NADPH to form sugars
Can Krebs cycle occur in the dark?
Kreb's cycle is part of cellular respiration, it needs nothing but oxygen and glucose. Only photosynthesis needs light.
Why do old biology textbooks called the carbon fixation reaction of photosynthesis the 'dark reaction'?
Though the reaction is not triggered by light, it does need the products produced in the "light-dependent " process.
What are platns that only use the calvin cycle for photosynthesis called?
C3 plants
Why do light reactions only occur during daylight?
Obviously, there is no sunlight energy for light dependent reactions to occur while calvin cycle AKA light independent phase does not require light as it uses energy in the form of ATP and the NADPH to form sugars
Does during dark phase does it need chlorophyll?
No, chlorophyll is not needed during the dark phase of photosynthesis. Chlorophyll is a pigment that absorbs light energy to drive the light-dependent reactions of photosynthesis, which only occur during the light phase. In the dark phase (or light-independent phase), known as the Calvin cycle, chemical reactions use ATP and NADPH produced during the light phase to convert carbon dioxide into glucose.
Why can the dark reaction occur in day light hours?
The dark reaction, also known as the Calvin cycle, can occur during daylight hours because it does not directly require light energy to proceed. It uses the ATP and NADPH generated during the light-dependent reactions to fix carbon dioxide and produce sugars. So even though it doesn't rely on light for its energy source, it still benefits from the products of the light-dependent reactions that happen during the day.
