Question

uses atp and nadph that were made during the _______ reactions. The number of molecules of atp used in step 1 is ______. The number of molecules of nadph used in step 2 is _______. When atp is used, it is converted to ________. In step 2, adp and nadp are formed, and then they can be used again in the _______ reactions to produce new atp and nadph. Step 3 completes the Calvin cycle. Rubp is replenished, and then it can be used again to fix (attach) more ________.

Answer 1

The Calvin cycle uses ATP and NADPH to produce GA3P molecules, which store energy. ADP and NADP are formed in step 2 and can be used again in the light reactions. Step 3 of the Calvin cycle replenishes RuBP for further carbon fixation.

Step-by-step explanation:

The Calvin cycle harnesses energy in the form of 6 ATP and 6 NADPH that are used to produce glyceraldehyde-3-phosphate (GA3P) molecules. These molecules store the energy captured from photosynthesis. During step 1 of the Calvin cycle, ATP is converted to ADP, while in step 2, ADP and NADP are formed. ADP and NADP can be used again in the light reactions to produce new ATP and NADPH. Step 3 of the Calvin cycle completes the cycle by replenishing RuBP, which can be used again to fix more carbon dioxide.
