Calvin cycle occurs in the stroma of the chloroplast and utilizes the NADPH and ATP produced in the process of light dependent reaction( or what we say the z- scheme reaction). If both are present then the Calvin cycle can occur even at night. because the Calvin cycle is light independent reaction.
whereas the photo system as asked in the question actually refers to light dependent reaction( or what we say the z- scheme reaction) requires light.
What else can I help you with?
The Calvin cycle happens during?
Carbon dioxide fixation in the light independent Calvin cycle occurs at night. Rubisco enzyme catalyzes the fixation of carbon dioxide to ribulose-1-5- bisphosphate.
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.
Where do extra ATP molecules come from in the Calvin Cycle?
The extra ATP molecules needed for the Calvin Cycle come from the light-dependent reactions of photosynthesis, specifically from the electron transport chain in the thylakoid membrane. Here, the energy from sunlight is used to generate ATP through the process of photophosphorylation.
Plants that fix CO2 into organic acids at night when the stomata are open and carry out the Calvin cycle during the day when the stomata are closed are called?
Plants that fix CO2 into organic acids at night when the stomata are open and carry out the Calvin cycle during the day when the stomata are closed are called CAM (Crassulacean Acid Metabolism) plants. CAM plants have adapted their carbon fixation process to avoid water loss during the day by keeping stomata closed, and perform photosynthesis during the night when conditions are cooler and less water loss occurs.
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.
Why can the Calvin cycle work at night but photosystems cant?
Because photosystems need light to operate (photo=light). Photosystems use energy from sunlight, Calvin systems use energy stored in the plant.
What part of the photosynthesis an occur at night?
Calvin cycle
Which photosynthetic can occur at night?
apex: the Calvin cycle
Which photosynthetic process can occur at night?
apex: the Calvin cycle

Why is possible for Calvin cycle to occur in the dark?
The Calvin cycle is called the dark cycle because it does not require light to proceed. Unlike light reactions, the Calvin cycle is a light-independent reaction, which means it can and will occur in the dark as well as the light.
Which process of photosynthesis can occur at night?
During the night, the biochemical process of CAM (Crassulacean Acid Metabolism) photosynthesis can occur in certain plants. This process involves storing carbon dioxide taken up during the night in the form of organic acids, which are then used during the day for photosynthesis. CAM plants close their stomata during the day to reduce water loss, and then open them at night to take up carbon dioxide.
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
Does the Calvin cycle only occur in the dark?
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 :)
