What else can I help you with?
What two reactions occur in photosynthesis?
There are three carbon dioxide, water, and sunlight.
Why can the dark reaction occur in day light hours?
The dark reaction, also known as the Calvin cycle, can occur during daylight hours because it does not directly require light energy to proceed. It uses the ATP and NADPH generated during the light-dependent reactions to fix carbon dioxide and produce sugars. So even though it doesn't rely on light for its energy source, it still benefits from the products of the light-dependent reactions that happen during the day.
Why does fluorescence occur when a solution of chlorophyll absorbs light recall the light dependent reactions in the intact chloroplast?
It does this because the two substances have a chemical reaction which allows the colour to get brighter
Why can the Calvin cycle work at night but the photosystems connot?
Calvin cycle occurs in the stroma of the chloroplast and utilizes the NADPH and ATP produced in the process of light dependent reaction( or what we say the z- scheme reaction). If both are present then the Calvin cycle can occur even at night. because the Calvin cycle is light independent reaction. whereas the photo system as asked in the question actually refers to light dependent reaction( or what we say the z- scheme reaction) requires light.
When during the light reaction is the water molecule split?
The water molecule is split at the beginning of the light reaction, specifically in photosystem II. This splitting of water releases electrons, protons, and oxygen as byproducts, which are essential for the rest of the light-dependent reactions to occur.
Where does light-dependent reaction HAPPENED?
They occur in the thylakoid membranes of the chloroplasts in plant cells.
What two types of reactions occur during photosynthesis?
The two reactions which occur during photosynthesis are light reaction and dark reaction. Light reaction takes place only in the presence of light. Dark reaction can occur with or without light.
How does light play a role in photosynthesis?
Causes the photolysis of water and enables the calvin cycle to occur or the light-dependent reaction of photosynthesis.
What Will Most Likely Happen To a Plant That Does Not Does Not Receive Any Water?
The light-dependent reactions will not occur.
What two reactions occur in photosynthesis?
There are three carbon dioxide, water, and sunlight.
Why is possible for Calvin cycle to occur in the dark?
The Calvin cycle is called the dark cycle because it does not require light to proceed. Unlike light reactions, the Calvin cycle is a light-independent reaction, which means it can and will occur in the dark as well as the light.
What is the difference between the light dependent reactions and the light independent reactions?
light dependent reactions only occur in light this means thier reations increases with light intensity while light independent can occur in the dark
Why can the dark reaction occur in day light hours?
The dark reaction, also known as the Calvin cycle, can occur during daylight hours because it does not directly require light energy to proceed. It uses the ATP and NADPH generated during the light-dependent reactions to fix carbon dioxide and produce sugars. So even though it doesn't rely on light for its energy source, it still benefits from the products of the light-dependent reactions that happen during the day.
Compare and contrast light dependent and light independent reactions of photosynthesis.?
Light-dependent reactions occur in the thylakoid membrane and require light energy to produce ATP and NADPH. Light-independent reactions (Calvin Cycle) occur in the stroma and use ATP and NADPH to convert CO2 into glucose. Both processes are essential for photosynthesis and occur in chloroplasts.
Where do the light dependent occur?
On the thylakoid membrane :)
Why does fluorescence occur when a solution of chlorophyll absorbs light recall the light dependent reactions in the intact chloroplast?
It does this because the two substances have a chemical reaction which allows the colour to get brighter
What is the difference between light-dependent reactions and light-independent?
