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 :)

Can auroras only occur at night?
Auroras can occur during the day or night, but they are typically easier to see at night when it is dark. However, strong solar activity can sometimes create auroras that are visible during the daytime as well.
How often do the northern lights occur?
The northern lights, or aurora borealis, occur frequently in high-latitude regions, such as the Arctic Circle. They are most commonly seen in the fall and spring, but can occur throughout the year depending on solar activity and geomagnetic conditions.
What are dark areas on the photosphere on the sun called?
Dark areas on the photosphere of the Sun are called sunspots. They appear dark because they are cooler regions compared to their surrounding areas, which results in decreased luminosity. Sunspots are temporary phenomena that occur in 11-year cycles as part of the Sun's magnetic activity.
Do they like sleeping in the dark only or with a light?
do they like sleeping in the dark only or with light
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).
Does the Calvin cycle occur only in the dark?

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?
The Calvin cycle is sometimes called the dark reactions because it does not require light directly and can occur in the absence of sunlight. The cycle takes place in the stroma of chloroplasts and uses ATP and NADPH produced during the light-dependent reactions to convert carbon dioxide into glucose.
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.
