What is the relationship between the light dependent reaction and Calvin cycle?
The two reactions of photosynthesis are connected by two substances: ATP and NADPH. These are produced by the light dependent reaction and are used by the light independent reaction. ATP is produced from ADP and Pi (phosphate): ADP + Pi ---> ATP This reaction requires energy to make it work, and this energy comes from light absorbed in the light dependent reaction. NADPH is produced from NADP+ and H: NADP+ + H ---> NADPH This reaction also requires energy, which is obtained from light in the light dependent reaction. The ATP and the NADPH are used in the light dependent reaction to provide energy and a source of H to convert CO2 to CH2O (carbohydrate). The products of the reactions (ADP, Pi, NADP+) are recycled in the light dependent reaction to produce more ATP and NADPH.

Why is the light dependent reactions called the light dependent reaction?
it is the first stage because the product of the light dependent reaction is ATP and NADPH+H+ (Nicotinamide Adenine Dinucleotide Phosphate Hydrogen) and these are required in the light independent reaction (calvin-benson cycle) I hope this helps :DDD
What does light dependent reaction need to proceed?
The light-dependent reaction can only occur in the light because light supplies the energy needed for the reaction. In this stage of photosynthesis, light energy is converted into chemical energy (ATP) and 'reducing power' (NADPH) which are then used in the light-independent reaction. Also in the light-dependent reaction, water is split to provide the hydrogen needed to make NADPH. The light-independent reaction can take place in the light andthe dark, i.e., it is independent of the light! However, it needs the products of the light-dependent reaction (ATP and NADPH), so it cannot continue indefinitely without it. In the light-independent reaction, the ATP and NADPH produced by the light-dependent reaction are used to convert carbon dioxide into carbohydrate, e.g., glucose. This happens in a series or reactions called the Calvin cycle. A link is provided.
Atp and nadph molecules generated during the light reactions power the dark reactions?
True. In the light reaction ATP and NADPH(2) molecules are created, then in the dark reaction they are used.
What molecules do plants take in to begin the Calvin cycle?
Plants take in carbon dioxide from the atmosphere to begin the Calvin cycle. They also use ATP (adenosine triphosphate) and NADPH (nicotinamide adenine dinucleotide phosphate) molecules, which are generated during the light-dependent reactions of photosynthesis, to power the Calvin cycle.

What comes out of light reactions?
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 released2) the light-independent stage uses the products of the light-dependent stage (ATP and NADPH) to reduce carbon dioxide to carbohydrate

How do the light dependent reactions of photosynthesis relate to the Calvin cycles?
The light dependent reactions create compounds which store the energy necessary for the Calvin Cycle to take place. This energy is stored in ATP (Adenosine Triphosphate), among other compounds, during the LDR. In the Calvin cycle, these are broken down, which releses energy. The energy released is used to create bonds between the parts of Glucose Another way to explain it in a simpler way is, when the light reaction has gone through once, it has produced NADH and ATP. These are nessisary for the making of glucose which is what the Calvin cycle does. The NADH and ATP are what power the Calvin cycle.
What are the reactions of photosynthesis?
light reaction and dark reaction
What molecules are used to power dark reactions What molecule does this energy breakdown?
NADPH2 and ATP produced during photolysis of water in light reaction are used to power dark reactions of photosynthesis in which CO2 is assimilated to form glucose.
Water and energy from the sun to photosynthesis.?
Photones are used to break an electron free from a chlorophyll molecule, then the electron goes through very complexed series of reactions called light-dependent reactions after which ATP (energy) is synthetised. So light energy is used to power photosynthesis.
How is H2O involved in photosynthesis?
The water is split in the light reactions, with the H+ being used to reduce NADP to NADPH, thereby storing energy which will power the Calvin Cycle, which makes carbohydrates. The result of the light reactions is also oxygen gas, O2.
What is function and structure of stroma?
The stroma of a plant is the region outside of the thylakoid space. This serves two functions in the both the light-dependent and light-independent (Calvin cycle) reactions. In the light-dependent reactions, the H+ ions that build up within the thylakoid begin to form a concentration gradient between the thylakoid and the stroma. As a result, the H+ ions need to diffuse into the stroma. In order to do this, the ions must travel through an enzyme known as ATP synthase. Once it does, the movement of H+ ions through ATP synthase into the stroma provides energy for ADP to become ATP. The ATP formed is an energy source to power the Calvin cycle. Now, the light-independent (Calvin cycle) reactions occur in the stroma.
What molecules do plants take in to begin the Calvin cycle?
Plants take in carbon dioxide from the atmosphere to begin the Calvin cycle. They also use ATP (adenosine triphosphate) and NADPH (nicotinamide adenine dinucleotide phosphate) molecules, which are generated during the light-dependent reactions of photosynthesis, to power the Calvin cycle.
