Question

The light-independent reactions of photosynthesis, also known as the Calvin cycle, must repeat six times in order for a cell to have enough material to construct a complete glucose molecule. A variety of molecules are used and produced during this process.Sort the molecules below into three categories; molecules brought in and used in six turns of the Calvin cycle, molecules produced during six turns of the Calvin cycle that leave the cycle, and molecules used and regenerated within the Calvin cycle during six turns.Molecules:a. 10G3P b. CO2 c. 12NADPH d. 18ADP e. 6RuBP f. 2G3P g. 18ATP h. 12NADPH^+ + 12H^+

Answer 1

Answer:

Molecules brought in: 3CO2, 9ATP, 6NADPH

Molecules Produced: 1G3P, 9ADP, 6NADP+ +H+

Molecules used and Regenerated: 3RuBP, 5G3P

Explanation:

1. Molecules brought in and utilized in the light-independent reaction or Calvin cycle:

-CO2 from outside the cell

-Molecules take energy from the light-dependent reactions

2. Molecules produced during the light-independent reaction or Calvin cycle that leave the cycle:

-Energy-carrier molecules that have lost some energy\

-3-carbon molecules that store energy

3. Molecules produced in the cytoplasm from the end products of the Calvin cycle:

-Organic molecules such as glucose

Thus, Molecules brought in: 3CO2, 9ATP, 6NADPH

Molecules Produced: 1G3P, 9ADP, 6NADP+ +H+

Molecules used and Regenerated: 3RuBP, 5G3P
