Which part of the chloroplst does the light dependent reaction occur?
The light-dependent reactions of photosynthesis occur in the thylakoid membrane of the chloroplast. Pigments like chlorophyll absorb light energy, which is then used to generate ATP and NADPH.
What two reactions occur in photosynthesis?
There are three carbon dioxide, water, and sunlight.
How will light affect photosynthesis?
Light allows photosynthesis to occur. Therefore more light=faster reaction.
Where does light dependent occur in the chloroplast?
Light- independent reactions of photosynthesis occur in the stroma of the chloroplasts of a cell.
Which part of photosynthesis can occur even when there is no light?
That is the dark reaction. It needs no light
How does light play a role in photosynthesis?
Causes the photolysis of water and enables the calvin cycle to occur or the light-dependent reaction of photosynthesis.
What two types of reactions occur during photosynthesis?
The two types of reactions that occur during photosynthesis are light-dependent reactions and light-independent reactions (Calvin cycle). Light-dependent reactions require light energy to produce ATP and NADPH, while light-independent reactions use ATP and NADPH to convert carbon dioxide into glucose.

What type of chemical reaction is 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.
What are the light independent and dependent stages of photosynthesis?
The light-dependent stage of photosynthesis occurs in the thylakoid membranes of chloroplasts, where light energy is absorbed to produce ATP and NADPH. In the light-independent stage (Calvin cycle), these products are used to convert carbon dioxide into glucose in the stroma of the chloroplasts.
Does the photosynthesis reaction occur in the presence of artificial light?
Yes of course
Can the light dependant reactions occur without the light independent reactions?
No, the light-dependent reactions of photosynthesis cannot occur without the light-independent reactions. The light-dependent reactions generate ATP and NADPH, which are essential for the light-independent reactions to convert carbon dioxide into sugars through the Calvin cycle. Both sets of reactions are interconnected and crucial for the overall process of photosynthesis.
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.
