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 :)

How often do the northern lights occur?
The Northern Lights occur year round but are only visible when nights are dark. In the locations in which they are best seen, Alaska, Canada, Norway and Finland, they are usually seen from September through April when the nights are long and dark.
Do they like sleeping in the dark only or with a light?
do they like sleeping in the dark only or with light
Can color be seen in the dark?
No, color can not be seen in the dark. The only color that can be seen in the dark is black, because it is dark. If it is not completely dark then you might be able to see the color of some objects.
Do eclipses occur during full moons?
No. To get a solar eclipse the moon has to be in a position between the sun and the earth, this happens only round the time of the new moon (when there is little or no moon visible). When the moon is full, the earth is between the sun and the moon (there could therefore be a "lunar" eclipse).
Why is the Moon dark all of the time?
The moon is not dark all the time. It is dark in a phase called a "new moon." But it only temporarily lasts.
Does the Calvin cycle occur only 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 :)
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.
Do the of photosynthesis ocdark reactions cur only at night?
No, dark reactions occurs in day light & as well as in night. It cant be called as dark reaction, its a Calvin cycle.
What requires CO2?
Calvin Cycle only
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.
Does photophosphorylation occur in only prokaryotes?
No, it takes place in both prokaryotes and eukaryotes
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
The dark reactions of photosynthesis are those that?
Only occur in the dark.
Which part of the photosynthetic process requires ATP NADPH and carbon dioxide to produce glucose?
The Calvin cycle
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
