What happens to NADPH and ATP after they are used in the Calvin Cycle?

the Calvin cycle uses ATP and NADPH to convert CO2to sugar: ATP and NADPH produced by the light reactions are used in the Calvin cycle to reduce carbon dioxide to sugar. • The Calvin cycle is similar to the Krebs cycle in that the starting material is regenerated by the end of the cycle.

explation the answer in that

step 1 ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. this is called nitrification. 2. step 2 the deer eats the plants and uses the nitrogen-containing proteins for cell growth. 3. step 3 bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium. 4. step 4 some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere. 5. step 5 nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification. 6. step 6 plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.
