What are the light reactions and where do they take place?
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 in the chloroplast do the light reactions occur quizlet?
– The light reactions take place inside the thylakoids of chloroplasts. – The light reactions produce chemical energy in the form of NADPH and ATP.
Is light reaction takes place in the grana of chloroplast?
A light reaction takes place in the grana of chloroplast. It includes cyclic and non-cyclic photophosphorylation where assimilatory forces (ATP and 12NADPH2) are delivered.
What are the 4 steps of light reactions?
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.
Where in the chloroplast do the light reactions and Calvin cycle occur?
stroma
This process is fueled by, and dependent on, ATP and NADPH from the light reactions. Unlike the light reactions, which take place in the thylakoid membrane, the reactions of the Calvin cycle take place in the stroma (the inner space of chloroplasts).
What connects the two photosystems in the light reactions?
An electron transport chain connects the two photosystems in the light reactions.
What are the end products of light reaction?
What are the end products of light reactions?
- Hint: The process of using the energy in sunlight to make food (glucose) is known as photosynthesis.
- Complete answer:
- Therefore, the end products are ATP and NADPH.
- Note: The ATP and NADPH from the light-dependent reactions are used to make sugars in the Calvin cycle.
What is another name for the light reaction?
Other names for light-independent reactions include the Calvin cycle, the Calvin-Benson cycle, and dark reactions.
How many ATP are produced in light reaction?
The nine molecules of ATP and six molecules of NADPH come from the light reactions.
Where does the light reaction of photosynthesis take place?
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.
Where do the light-dependent reactions take place?
A. in the stroma of the chloroplast B. within the mitochondria membranes C. within the thylakoid membranes D. in the cell membrane of the chloroplasts Where do the light-dependent reactions take place?
Which is part of the chloroplast does each stage occur?
In the light stage of photosynthesis, the chloroplast absorbs the light of the sun. This sets off a series of chemical reactions, beginning by converting the sunlight to chemical energy. According to About.com, three types of energy are produced: ATP, NADPH and oxygen,…
Where does the Calvin cycle take place in chloroplast?
It takes place in the stroma of chloroplast in photosynthetic organisms. Calvin Cycle is a series of reaction, also known as the dark reactions, or light-independent reactions because they are not directly driven by light,
