The light reactions must occur prior to the dark reactions because they generate the essential energy carriers, ATP and NADPH, needed for the Calvin cycle. These energy-rich molecules are produced when chlorophyll absorbs sunlight, initiating the process of photosynthesis. The dark reactions, or Calvin cycle, rely on the ATP and NADPH from the light reactions to convert carbon dioxide into glucose. Without the light reactions, the energy and reducing power required for the dark reactions would not be available.

Do the dark reactions occur in the thylakoids?

A dark reaction is done in the Calvin Cycle. Light is not needed at the time of the dark reaction but it also doesn't hinder the reaction if there is light at the time.So in short. Yes.


Place where dark reactions occur?

Dark reactions, also known as the Calvin cycle, occur in the stroma of the chloroplasts in plant cells. This process involves the conversion of carbon dioxide into glucose using ATP and NADPH generated during the light reactions.


What is the difference between the light dependent and the dark reactions of the Calvin cycle?

The light-dependent reactions of the Calvin cycle require light to occur and take place in the thylakoid membranes of the chloroplast. These reactions generate ATP and NADPH. In contrast, the dark reactions (Calvin-Benson cycle) occur in the stroma of the chloroplast and use ATP and NADPH from the light-dependent reactions to fix carbon dioxide and produce sugars.


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.


Which part of a chloropast do the dark reactions occur you in?

The dark reactions of photosynthesis, specifically the Calvin cycle, take place in the stroma of the chloroplast. The stroma is the fluid-filled space surrounding the thylakoid membranes where the light-independent reactions occur to produce sugars using ATP and NADPH generated during the light reactions.

How are the dark reactions that occur in plants dependent on the light-reactions?

The dark reactions that occur in plants are dependent on the light reactions because the dark reactions need ATP and NADPH. ATP and NADPH are energy molecules that dark reactions need to do their job.


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.


What is the difference between the light dependent reactions and the light independent reactions?

light dependent reactions only occur in light this means thier reations increases with light intensity while light independent can occur in the dark


How are light reactions and dark reactions similar and different?

Differences: >light reactions occur in the thykaloid membranes, but dark occur in stroma >light reactions are light dependent, or they need light to take place, whereas dark reactions don't > dark reactions use the products of the light reactions >light reactions are the first step of photosynthesis and dark reactions are the second step Similarities: >both in photosynthesis Thats really the only similarity!!! hope this helps :)

What happens during each each of the two stages of photosynthesis?

These stages are called the light reactions and the dark reactions. The light reactions take place in the presence of of light. The dark reactions do not require direct light, however dark reactions in most plants occur during the day.

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.

light dependent reactions only occur in light this means thier reations increases with light intensity while light independent can occur in the dark


What two types of reactions occur during photosynthesis?

The two reactions which occur during photosynthesis are light reaction and dark reaction. Light reaction takes place only in the presence of light. Dark reaction can occur with or without light.


In what organelle do light reactions occur in plants?

Light reactions in plants occur in the thylakoid membrane of the chloroplasts. This process involves capturing light energy and converting it into chemical energy in the form of ATP and NADPH, which are used in the Calvin cycle to produce sugars.
