Where do the light reactions of photosynthesis occur quizlet?
The light-dependent reactions take place on the thylakoid membranes (the light is absorbed by the chlorophyll that is embedded in these membranes). The light-independent reactions (also called the Calvin Cycle or the dark reactions) take place in the stroma. The stroma is the fluid that fills the chloroplast.
Where do light reactions occur in the thylakoid?
In photosynthesis, the light-dependent reactions take place on the thylakoid membranes. The inside of the thylakoid membrane is called the lumen, and outside the thylakoid membrane is the stroma, where the light-independent reactions take place.
Where do the dark and light reactions occur in photosynthesis?
The light reactions of photosynthesis take place in the thylakoid membrane, whereas the dark reactions are located in the chloroplast stroma.
Where do the light-dependent reactions of photosynthesis occur in the chloroplast quizlet?
In photosynthesis, the light-dependent reactions take place on the thylakoid membranes. The inside of the thylakoid membrane is called the lumen, and outside the thylakoid membrane is the stroma, where the light-independent reactions take place.
What are the inputs of light reactions?
1. For each of the two main stages of photosynthesis, identify the inputs. Inputs of the light reactions are light and water, and ADP, P, and NADP+ from the Calvin cycle. Inputs of the Calvin cycle are CO2, and ATP and NADPH from the light reactions.
Where does the light reaction occur in 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.
What three reactions occur during the light reactions in photosynthesis?
Here are the basic steps:
- Light absorption in PSII. When light is absorbed by one of the many pigments in photosystem II, energy is passed inward from pigment to pigment until it reaches the reaction center. …
- ATP synthesis. …
- Light absorption in PSI. …
- NADPH formation.
What is the light reaction in photosynthesis?
Light reaction is the first stage of photosynthesis process in which solar energy is converted into chemical energy in the form of ATP and NADPH. The protein complexes and the pigment molecules help in the production of NADPH and ATP.
Where does light reaction takes place in chloroplast Class 10?
Light reaction takes place in the ribosome of the chloroplast.
Where do the light-dependent reactions and the Calvin cycle occur?
The reactions that make up the process of photosynthesis can be divided into light-dependent reactions, which take place in the thylakoids, and light-independent reactions (also known as dark reactions or the Calvin cycle), which take place in the stroma.
Where do Calvin cycle reactions occur?
stroma
Explanation: The Calvin cycle takes place in the stroma area in the chloroplasts. The mitochondria is another organelle, and the nucleus contains the DNA. The thylakoids are in the chloroplasts and contain the pigment chlorophyll in which the light reactions occur.
