Question

Following carbon atoms around the Calvin cycle. The net reaction of the Calvin cycle is the conversion of CO2 into the three-carbon sugar G3P. Along the way, reactions rearrange carbon atoms among intermediate compounds and use the ATP and NADPH produced by the light reactions. In this exercise, you will track carbon atoms through the Calvin cycle as required for the net production of one molecule of G3P. For each intermediate compound in the Calvin cycle, identify the number of molecules of that intermediate and the total number of carbon atoms contained in those molecules. As an example, the output G3P is labeled for you: 1 molecule with a total of 3 carbon atoms. Labels may be used once, more than once, or not at all.
a. 3 molecules 3 carbon.
b. 6 molecules 18 carbon.
c. 6 molecules 18 carbon.
d. 5 molecules 15 carbon.
e. 3 molecules 15 carbon.
f. 3 molecules 15 carbon.

Answer 1

Answer:

Explanation:

The Calvin cycle represent the second phase of photosynthesis ( the dark phase of the reaction not because it is dark but because it not dependent on light). The ATP and NADPH produced in the light dependent phase used to synthesize glucose. The intermediates and there carbon content are stated below:

3 molecules of carbon dioxide    total carbon = 3 carbon

6 molecules of 3-phosphoglycerate   total carbon = 18 carbon

6 molecules of 1,3-Bisphosphoglycerate total carbon = 18 carbon

5 molecules of glyceraldehyde -3-phosphate  total carbon = 15 carbon

3 molecules of Ribulose-5-phosphate            total carbon = 15 carbon

3 molecules of Ribulose-1,5-bisphosphate    total carbon = 15 carbon
