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)
The products of the photosystems are the reactants for the Calvin cycle.Students who are using this as a resource for APEX coursework should note that you may want to paraphrase so your teachers can't google your responses :)
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
The light reactions provide the energy carriers used in the Calvin cycle
The simplest look of photosynthesis will show that there are two photosystems. Photosystem II, P680, is important in initiating photosynthesis by exciting electrons to move down the electron transport chain. 680 nm is the optimal wavelength of light for this photosystem. Photosystem I, P700, transfers electrons to ferrodoxin which transfers electrons to the ferrodoxin NADP+ reductase; the NADPH formed here will be used in the Calvin cycle. 700 nm is the optimal wavelength of light for which this photosystem is most active.

i dont know this one
to make energy-carrier molecules like NADPH Apex
It will not work properly, but there are usually electrons from the carbon dioxide and water needed to perform the Calvin Cycle at all.

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.

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.
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.
