What chemical reaction occurs in the chloroplasts?
Photosynthesis
Photosynthesis occurs in the chloroplast, an organelle specific to plant cells. The light reactions of photosynthesis occur in the thylakoid membranes of the chloroplast. Electron carrier molecules are arranged in electron transport chains that produce ATP and NADPH, which temporarily store chemical energy.
Why does light reaction occur in chloroplast?
The chloroplast is involved in both stages of photosynthesis. The light reaction takes place in the thylakoid discs. In this reaction, the energy from ATP and NADPH are used to fix carbon dioxide (CO2).
What occurs in the light reaction of photosynthesis?
Photosynthesis begins with the light reactions. The energy is then temporarily transferred to two molecules, ATP and NADPH, which are used in the second stage of photosynthesis. ATP and NADPH are generated by two electron transport chains. During the light reactions, water is used and oxygen is produced.
What Does the light-independent reaction occur?
Where do light-independent reactions occur? The Calvin cycle or light-independent reaction of photosynthesis happens in the stroma of the chloroplast. It has certain enzymes that work with NADPH and ATP. They form carbon-containing molecules (such as glucose molecules) from carbon dioxide.
Where does the light-dependent reaction occur in the chloroplast?
Light-dependent reactions happen in the thylakoid membrane of the chloroplasts and occur in the presence of sunlight. The sunlight is converted to chemical energy during these reactions. The chlorophyll in the plants absorb sunlight and transfers to the photosystem which are responsible for photosynthesis.
In which part of chloroplast dark reaction occurs?
stroma
Dark reactions of photosynthesis are the chemical reactions that convert carbon dioxide and other compounds into glucose. These reactions occur in the stroma. Stroma is a fluid filled area of a chloroplast outside the thylakoid membrane.
Where does the light reaction and dark reaction occur in the chloroplast?
Light reaction and dark reaction are the two types of sequential processes that occur during the photosynthesis of plants. Light reaction occurs in the thylakoid membrane of chloroplast whereas the dark reaction occurs in the stroma of the chloroplast.
What are the steps in light reactions?
There are three phases to the light-independent reactions, collectively called the Calvin cycle : carbon fixation, reduction reactions, and ribulose 1,5-bisphosphate regeneration. Despite its name, this process occurs only when light is available.
Where does the light reaction occur?
Light reaction is the stage of photosynthesis which occurs only in the presence of sunlight and it is dependent on the light to perform its work. it takes place in the grana thylakoid membrane of the chloroplast. the grana thylakoid is responsible for trapping the solar energy for photosynthesis.
What is the light reaction cycle?
Light reaction in photosynthesis is light-dependent whereas the Calvin cycle (or dark reaction in photosynthesis) is light-independent. Photosynthesis is an autotrophic mode of nutrition occurring in plants and other photosynthetic organisms such as algae and cyanobacteria . It is an anabolic process of producing food.
What is a light dependent reaction?
Light dependent reaction. [[Light dependent reaction]] The reaction taking place in the chloroplast in which the absorption of a photon leads to the formation of atp and nadph.
