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

During the light reactions of photosynthesis, the products are ATP, NADPH, and oxygen. ATP and NADPH are energy carriers that are used in the Calvin cycle to convert carbon dioxide into glucose. Oxygen is a byproduct released as a waste product into the atmosphere.

How do the light reactions and dark reactions work together?
The light reactions provide energy carriers for the dark reactions.
The two major sets of reactions involved in photosynthesis are?
The two major sets of reactions involved in photosynthesis are the light-dependent reactions and the light-independent reactions (Calvin cycle). In the light-dependent reactions, light energy is used to produce ATP and NADPH, while in the Calvin cycle, ATP and NADPH are used to convert carbon dioxide into glucose.
Where does the energy for the light independent reactions of photosynthesis come from?
splitting of water molecules
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 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
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 two major sets of reactions involved in photosynthesis are?
The two major sets of reactions involved in photosynthesis are the light-dependent reactions and the light-independent reactions (Calvin cycle). In the light-dependent reactions, light energy is used to produce ATP and NADPH, while in the Calvin cycle, ATP and NADPH are used to convert carbon dioxide into glucose.
How do the light reactions and dark reactions work together?
The light reactions provide energy carriers for the dark reactions.
Where does the energy come from to make NADPHin the light reactant?
The energy to make NADPH in the light reactions of photosynthesis comes from sunlight. Light energy is absorbed by chlorophyll molecules in the chloroplasts of plant cells, which triggers a series of reactions that ultimately produce NADPH.
Where does the energy for the light independent reactions of photosynthesis come from?
splitting of water molecules
How are light dependent and independent reactions related?
The products of light-dependent reactions are used in 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 :)
Where convert light reactions within the chloroplast?
Photosynthesis consists of light-dependent reactions and light-independent reactions. These light reactions occur within the chloroplast thylakoids, where the aforementioned chlorophyll pigments are found.
