Question

Write the equation for the production of one hexose sugar molecule from carbon dioxide

Answer 1

Answer;

6CO2 + 18ATP + 12 NADPH → C6H12O6 + 18ATP + 18Pi + 12NADP+

Explanation;

-The process of Calvin Cycle Synthesizes Hexoses from Carbon Dioxide and Water.

-The ATP and NADPH molecules produced by the light-dependent reactions of photosynthesis power sugar synthesis in the Calvin cycle. In the Calvin cycle, three molecules of CO2 are added to three molecules of ribulose bisphosphate (RuBP), a 5-carbon sugar already present in the stroma.

-This results to a total of eighteen carbons in the cycle.  As the three RuBP molecules accept a molecule of carbon dioxide, they immediately break down into six 3-carbon molecules of phosphoglyceric acid which is a hexose.

Answer 2

Answer: The equation for C3 cycle (calvin cycle) is 6RuBP + 6CO2 + 18ATP + 12 NADPH >->-> 6 RuBP + C6H12O6 + 18ATP + 18Pi + 12NADP+ 6CO2 molecules are needed to synthesise for one molecule of C2H12O6
