What chemical reaction happens in the chloroplast?
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.
What is the reaction of photosynthesis in the chloroplast?
The chloroplast is involved in both stages of photosynthesis. The light reactions take place in the thylakoid. There, water (H2O) is oxidized, and oxygen (O2) is released. The electrons that freed from the water are transferred to ATP and NADPH.
What is the major reaction that occurs in the chloroplast?
Photosynthesis occurs in the chloroplast of the plant cell. Carbon dioxide, water, and the sun’s energy are necessary for the chemical reactions of photosynthesis. The products of photosynthesis are glucose and oxygen.
What two reactions happen in the chloroplast?
The Chloroplast. Photosynthesis, the process of turning the energy of sunlight into ”food,” is divided into two basic sets of reactions, known as the light reactions and the Calvin cycle, which uses carbon dioxide.
Which of these reaction occurs in photosynthesis?
The two stages of photosynthesis: Photosynthesis takes place in two stages: light-dependent reactions and the Calvin cycle (light-independent reactions). Light-dependent reactions, which take place in the thylakoid membrane, use light energy to make ATP and NADPH.
What are the two reactions that take place during photosynthesis?
Within the chloroplasts of a plant cell, photosynthesis occurs in two main phases: the light-dependent and light-independent reactions.
What 2 reactions occur during photosynthesis?
What reaction occurs in photosynthesis?
Where does light reaction take place in chloroplasts?
Light reaction occurs in grana while dark reaction takes place in the stroma of chloroplasts. Photosynthesis is the process in which plants obtain energy from the sun and food in the form of sugar is prepared.
How are chloroplasts used in the Hill reaction?
To investigate photosynthesis using isolated chloroplasts (the Hill reaction). Amount of DCPIP reduced (can be judged based on the colour of the mixture) Use chloroplasts from the same species of plant – chopped spinach leaves can be used
How are chloroplasts used in the synthesis of food?
Absorbs light energy and converts it into chemical energy. Chloroplast has a structure called chlorophyll which functions by trapping the solar energy and used for the synthesis of food in all green plants. Produces NADPH and molecular oxygen (O 2) by photolysis of water.
Can a chloroplast reproduce independently from the rest of the cell?
Chloroplast has its own DNA and can reproduce independently, from the rest of the cell. They also produce amino acids and lipids required for the production of chloroplast membrane. The chloroplast diagram below represents the chloroplast structure mentioning the different parts of the chloroplast.
