No. Photosystems I and II are where light-dependent reactions occur, while the Calvin Cycle is where light-independent reactions occur. Photosynthesis begins with Photosystem II, then Photosystem I, then the products from there go to the Calvin Cycle. (yes photosystem II comes before photosystem I)

Photosystem I and Photosystem II are involved in the light reactions of photosynthesis. Photosystem II absorbs light energy to split water molecules and produce ATP, while Photosystem I absorbs light energy to produce NADPH. Both ATP and NADPH are then used in the Calvin cycle to convert carbon dioxide into glucose. Without the products of the light reactions, the Calvin cycle cannot proceed.

∙ 13y agoNo, Photosystems I and II are complexes that take part in the light reactions of photosynthesis, NOT the Calvin cycle.

How does photosystem II and photosystem allow the Calvin cycle to work?
Photosystem II and photosystem I are involved in the light-dependent reactions of photosynthesis, which generate ATP and NADPH. These products are essential for the Calvin cycle to function properly. ATP and NADPH provide the energy and reducing power needed for carbon fixation and synthesis of sugars during the Calvin cycle.
Why doesn't Calvin cycle occur at night?
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
How do the reactions and Calvin cycle work together to build glucose?
The light reactions provide the energy carriers used in the Calvin cycle
Which photosynthetic will be least affected by shorter periods of daylight?
the Calvin cyclethe calvin cycle
How many photosystems are involved during the light reaction of photosynthesis?
There are two photosystems, Photosystem I and Photosystem II, involved during the light reaction of photosynthesis. They work together in the thylakoid membrane to convert light energy into chemical energy by transporting electrons and generating ATP and NADPH.

How does photosyentgheis allow the Calvin cycle to work?
i dont know this one
Which is role of photosystem in the light reactions?
to make energy-carrier molecules like NADPH Apex
How does the lack of electrons affect the Calvin cycle?
It will not work properly, but there are usually electrons from the carbon dioxide and water needed to perform the Calvin Cycle at all.

What does the electron transport produce?
The Electron Transport Chain produces ATP. Extra Information: The ATP produced by the ETC is used in the Calvin Cycle. The Calvin Cycle requires CO2 and NADPH as well for it to work. The Calvin Cycle then produces Glucose (Sugars). The left over Glucose is then used and made as Starch.

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.
What is melvin calvin famous for?
Melvin Calvin was a Nobel Prize-winning American biochemist known for his discoveries on the carbon dioxide assimilation in plants, particularly the Calvin cycle, which is a series of chemical reactions that occur during photosynthesis. His work significantly advanced our understanding of how plants convert carbon dioxide into organic compounds using energy from sunlight.
