Which reaction in photosynthesis is light independent?
Calvin cycle
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.
Is photosynthesis light dependent or light independent?
Figure: 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 is an important difference between light dependent and light-independent reactions?
Which is an important difference between light-dependent (L-D) and light-independent (L-IND) reactions in photosynthesis? The L-D reactions need CO2 and light energy, and the L-IND reactions needs water and O2. The L-D reactions require light energy and water, and the L-IND reactions require ATP, NADPH and CO2.
What are the three major light-independent reactions in photosynthesis?
The light-independent reactions (also known as the Calvin cycle) can be organized into three basic stages: fixation, reduction, and regeneration (Video 13.6.
Where does light dependent reaction occur?
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.
What three reactions occur during the light reactions in photosynthesis?
The events occurring in the light reaction of the photosynthesis are: Absorption of sunlight by the chlorophyll and release of the electron to the carriers. Photolysis of water to provide the electron to the chlorophyll. The release of molecular oxygen due to the photolysis of water.
Why is the photosynthesis a light dependent reaction occur before the light independent reaction?
In light dependent photosynthesis, the photosynthetic pigment absorb the light energy and convert it into chemical energy, ATP and NADPH,. So the light dependent reaction should occur before the light independent reaction.
Which of the following is an important difference between the light-dependent and the light independent dark reactions of photosynthesis?
What is the difference between light and dark reaction? The light reaction is the initial stage of photosynthesis which traps light energy to produce ATP and NADPH, whereas dark reaction is the second step of photosynthesis which utilizes the energy from ATP and NADPH to produce glucose.
What is the main purpose of light-dependent reactions of photosynthesis?
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 the difference between light dependent and light independent reactions?
The difference between light independent and light dependent is that light independent doesn’t need light to make energy and light dependent does. light dependent reaction gets energy from the light, and light independent reactions is reactions to fix carbon and to use the energy to produce glucose.
What happens during light independent stage of photosynthesis?
Photosynthesis occurs in two stages. In the first stage, light-dependent reactions or light reactions capture the energy of light and use it to make the energy-storage molecules ATP and NADPH . During the second stage, the light-independent reactions use these products to capture and reduce carbon dioxide.
What are the reactants of light dependent?
LIGHT-DEPENDENT REACTIONS. The exergonic (def) light-dependent reactions of photosynthesis convert light energy into chemical energy, producing ATP and NADPH . These reactions occur in the thylakoids of the chloroplasts. The products of the light-dependent reactions, ATP and NADPH, are both required for the endergonic (def)…
Which two reactants are needed for light dependent reactions?
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 .
