How does the light reaction is different from light reaction?
Photosynthesis comprises two phases: The first phase is the photochemical phase or light-dependent process. This phase is commonly known as the light reaction….Difference between Light and Dark Reaction.
| Light Reaction | Dark Reaction |
|---|---|
| Photolysis occurs in PS-II. | Photolysis does not occur. |
What are the differences between light reactions and the Calvin cycle?
The key difference between light reaction and Calvin cycle is the dependence of light in each type of reaction in photosynthesis. Light reaction in photosynthesis is light-dependent whereas the Calvin cycle (or dark reaction in photosynthesis) is light-independent.
What are the two different light reactions?
Two types of reaction centers exist, generally called Photosystem I (PSI) and Photosystem II (PSII). Thus, two types of overall reactions make up photosynthesis—the light and dark reactions—while two more types of reactions compose the light reaction—those carried out by PSI and PSII.
What are the differences between the light-dependent reactions light reactions and the light-independent reactions dark reactions )?
The main difference between light and dark reaction is that light reaction is the first stage of photosynthesis, which traps light energy in order to produce ATP and NADPH whereas dark reaction is the second stage of photosynthesis, which produces glucose by using the energy form ATP and NADPH produced from the light …
What are the differences between light-dependent and light-independent reactions?
In the light-dependent reactions, energy from sunlight is absorbed by chlorophyll and that energy is converted into stored chemical energy. In the light-independent reactions, the chemical energy harvested during the light-dependent reactions drives the assembly of sugar molecules from carbon dioxide.
In what way are the light-dependent and light-independent reactions?
The light-dependent reactions convert light energy into chemical energy. The goal of the light-dependent reactions of photosynthesis is to collect energy from the sun and break down water molecules to produce ATP and NADPH. These two energy-storing molecules are then used in the light-independent reactions.
What is one of the main functions of light reactions?
The overall purpose of the light-dependent reactions is to convert solar energy into chemical energy in the form of NADPH and ATP. This chemical energy will be used by the Calvin cycle to fuel the assembly of sugar molecules.
What is light reaction Class 10th?
Light reaction is the reaction which occurs as the first phase of photosynthesis, in which energy in the form of light is absorbed and converted to chemical energy in the form of ATP…………… Niccherip5 and 16 more users found this answer helpful. Thanks 8.
In what way are light-dependent and light-independent reactions of photosynthesis similar?
The light-dependent reactions of photosynthesis use water and produce oxygen. The light-independent reactions release energy, and the light-dependent reactions require energy. The light-dependent reactions pass electrons through an electron transport chain to the light-independent reactions.
How are dark reactions different from light reactions?
The main difference between all such types gets explained in the following ways. The light-dependent reactions use light energy to make two molecules needed for the next stage of photosynthesis: the energy storage molecule ATP and the reduced electron carrier NADPH. Dark reactions make use of these organic energy molecules (ATP and NADPH).
Where does the dark reaction take place in a plant?
In the dark reaction, plants use carbon dioxide with ATP and NADPH from the light reactions to produce glucose. It takes place in the stroma of the chloroplast. What are the end products of light reactions?
How is Energy conserved in the light reaction?
In the photosynthetic light reactions, the energy of light is conserved as “high energy” phospho- anhydride bonds of ATP, and as reducing the power of NADPH. The proteins and pigments responsible for the photosynthetic light reaction get associated with the thylakoid (grana disk) membranes.
Which is formed during the light reaction in the Calvin cycle?
In the Calvin cycle, the ATP and NADPH formed during light reaction drives the reaction and convert six molecules of carbon dioxide into one sugar molecule, i.e. glucose. Following are the important differences between light and dark reaction:
