Photosynthesis takes place in twp major stages:
1) the light-dependent stage converts light energy into chemical energy (ATP) and reducing power (NADPH); in this process water is broken down and oxygen is released
2) the light-independent stage uses the products of the light-dependent stage (ATP and NADPH) to reduce carbon dioxide to carbohydrate

The two major sets of reactions involved in photosynthesis are?
Light Reactions and the Calvin Cycle Reactions.
How do the light reactions and dark reactions work together?
The light reactions provide energy carriers for the dark reactions.
What products from the light dependent reactions are used in the light independent reactions to make a 6 carbon sugar?
Glucose, NADP and ADP
When a green plant absorbs a toxic substance which inhibits the Calvin cycle How would this most likely affect the light reactions?
The light reactions would slow down.
What happens during 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.
What is meant by light reaction of photosynthesis or light phrase of photosynthesis?
The biochemical reactions involving photolysis of water comes under light reaction. It is infect a chain of reactions commonly known as light phase.
Why does the sun emit heat and light?
The heat and light emitted from the sun comes from the nuclear reactions that occur on it.
Where do the hydrogen ions comes from for the photosystems of the light-dependent reactions?
splitting of water molecules
The two major sets of reactions involved in photosynthesis are?
Light Reactions and the Calvin Cycle Reactions.
How do the light reactions and dark reactions work together?
The light reactions provide energy carriers for the dark reactions.
What kind of energy does photosynthesis start and end with?
Photosynthesis starts with the Light-Dependent reactions, which begins with radiant/light energy. By the time it has finished the Light-Independent Reactions, which comes after the dependent ones, it converts the light/radiant energy to glucose, or chemical energy.
The energy used in the Calvin cycle production of carbohydrates comes from?
ATP made by light reactions in photosynthesis
How are light dependent and independent reactions related?
The products of light-dependent reactions are used in light-independent reactions.
The initial reactions in photosynthesis are know as the?
The initial reactions in photosynthesis are the light dependent reactions and the light independent reactions
What are light light dependent reactions?
Light-dependent reactions are those that require light to proceed.
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 :)
How the light and dark reactions work together?
The light reactions provide energy carriers for the dark reactions.
