The Calvin cycle produces G3P, with the formula C3H7O6P. This is combined inside the chloroplast to make the six-carbon glucose sugar, C6H12O6. How many turns of the Calvin cycle would be required to build and produce a completed glucose molecule.

Six turns of Calvin cycle is required to produce one molecule of glucose.

Explanation:

The NADPH and ATP energy produced in the light reaction is used in the Calvin cycle to fix carbon present in CO2 into three-carbon organic compound called glyceraldehyde-3-phosphate.

Three turns of the Calvin cycle produce one molecule of glyceraldehyde-3-phosphate which is a three-carbon compound. Glucose is a six-carbon compound so 2 molecules of G-3-P will be required to make one glucose molecule.

Therefore to make two G-3-P six turns of the Calvin cycle is required.

the sugar-phosphate backbone forms the structural framework of nucleic acids, including dna and rna. this backbone is composed of alternating sugar and phosphate groups, and defines directionality of the molecule.

enhanced global partnerships and exploration capabilities may advance international preparedness for protecting the earth from catastrophic events such as some asteroid strikes, advancing collaborative research on space weather and protecting spacecraft by developing new means for space debris removal.
