Why does the Calvin cycle need the light reactions to keep going?

The Calvin cycle itself does not need light.
The Calvin cycle, also called the light independent stage of photosynthesis, uses ATP (energy) and NADPH (hydrogen) to convert carbon dioxide into carbohydrate (sugar). These reactions do not need light and can take place in the dark.
However in a plant the ATP and NADPH are produced by the light-dependent stage of photosynthesis. To produce these substances light is needed.
So although the Calvin cycle does not need light itself it does need substances made using light.

What are the dark reactions of photosynethesis also known as?
It is known as the Calvin cycle or light independent cycle
For the following questions compare the light reactions with the Calvin cycle of photosynthesis in plants?
Comparing the light reactions with the Calvin cycle of photosynthesis, which requires CO2?
What produces NAPDH compared to the light reactions with the Calvin cycle of photosynthesis in plants?
The light reactions produce NADPH, where the Calvin Cycle produces NADP+
What is the difference between the light dependent and the dark reactions of the Calvin cycle?
What is the difference between the light dependent and the dark reactions of the calvin cycle?
How does the Calvin cycle differ from the light-dependent reactions?
1. Calvin cycle takes place in the stroma and light- dependent reactions take place in the granum, also light is not required for all the reactions of Calvin cycle.2. Calvin cycle assimilates CO2 to form organic compounds whereas in light reactions photolysis of water leads the formation of energy rich inorganic compounds.
The two major sets of reactions involved in photosynthesis are?
Light Reactions and the Calvin Cycle Reactions.
Why are the reactions of the Calvin cycle also called the light-independent reactions?
because the Calvin cycle does not require light
What is another name for the dark reactions of photosynthesis?
Calvin cycle or light independent reaction
Why are the reactions of the Calvin cycle also called the light independent?
because the Calvin cycle does not require light
What are the two main stages for photosynthesis?
The light dependent stage and the light independent stage.
What does not belong in this phrase light dependent reactions Calvin cycle chlorophyll?
Calvin Cycle
What are the dark reactions of photosynethesis also known as?

What are light independent reactions called?
The main processes in the in dependant reactions are collectively called the Calvin Cycle.

What produces NAPDH compared to the light reactions with the Calvin cycle of photosynthesis in plants?
The light reactions produce NADPH, where the Calvin Cycle produces NADP+
The light reactions occur in the while the Calvin cycle occurs in the?
Light reactions occur in the thylakoid membranes while the Calvin cycle occurs in the stroma.
