What is the difference between the light dependent and the dark reactions of the Calvin cycle?
The light-dependent reactions of the Calvin cycle require light to occur and take place in the thylakoid membranes of the chloroplast. These reactions generate ATP and NADPH. In contrast, the dark reactions (Calvin-Benson cycle) occur in the stroma of the chloroplast and use ATP and NADPH from the light-dependent reactions to fix carbon dioxide and produce sugars.
What two reactions occur in photosynthesis?
There are three carbon dioxide, water, and sunlight.
Where do the different stages of photosynthesis occur in the cell?
The light-dependent reactions of photosynthesis occur in the thylakoid membranes of chloroplasts, while the light-independent reactions (Calvin cycle) occur in the stroma of chloroplasts.
How does the Calvin cycle differ from the light-dependent reactions?
1. Calvin cycle takes place in the stroma and light- dependent reactions take place in the granum, also light is not required for all the reactions of Calvin cycle.2. Calvin cycle assimilates CO2 to form organic compounds whereas in light reactions photolysis of water leads the formation of energy rich inorganic compounds.
Why do light reactions only occur during daylight?
Obviously, there is no sunlight energy for light dependent reactions to occur while calvin cycle AKA light independent phase does not require light as it uses energy in the form of ATP and the NADPH to form sugars
What is the difference between the light dependent and the dark reactions of the Calvin cycle?
The light-dependent reactions of the Calvin cycle require light to occur and take place in the thylakoid membranes of the chloroplast. These reactions generate ATP and NADPH. In contrast, the dark reactions (Calvin-Benson cycle) occur in the stroma of the chloroplast and use ATP and NADPH from the light-dependent reactions to fix carbon dioxide and produce sugars.
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.
Where in plants does photosynthesis happen?
It happens in the chloroplasts. The light-dependent reactions occur in the thylakoids. The calvin cycle (light-independent), occur in the stroma.
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.
Where in the chloroplast do the light dependent reactions take place?
They occur in the thylakoid membranes of the chloroplasts in plant cells. They are light dependent in that they need the energy given off by the sun to "excite" the electrons in order to move down the electron transfer chain, which ultimately prepares them to be used by NADP+ to form NADPH to assist in the light independent cycle. (Calvin Benson Cycle)
Where do the different stages of photosynthesis occur in the cell?
The light-dependent reactions of photosynthesis occur in the thylakoid membranes of chloroplasts, while the light-independent reactions (Calvin cycle) occur in the stroma of chloroplasts.
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
What is different between the Calvin cycle and light-dependent reactions?
Light dependent reactions take place in the thylakoid membrane. The Calvin Cycle takes place in the stroma. The light dependent reactions use light energy to make ATP and NADPH. The Calvin Cycle uses these to make CA3P and Co2.
What are the two steps in photosynthisis?
The two steps in photosynthesis are the light-dependent reactions, which occur in the thylakoid membranes and require light to produce ATP and NADPH, and the light-independent reactions (Calvin cycle) that occur in the stroma and use ATP and NADPH to convert CO2 into sugar.
What is the differences between the light dependent reactions?
The Calvin cycle occurs at any time of the day, while the light dependent reactions require light. The calvin cycle produces glucose, while the light dependent reactions produce oxygen, ATP, and NADPH. The calvin cycle occurs because of the products of the light dependent reactions.
