Question

How many times a calvin cycle is repeated to form a glucose molecule?

Answer 1

HOLA MATE!!

Therefore, there is only 1 net carbon produced to play with for each turn. To create 1 surplus G3P requires 3 carbons, and therefore 3 turns of the Calvin cycle. To make one glucose molecule (which can be created from 2 G3P molecules) would require 6 turns of the Calvin cycle.

Answer 2

6 turns of Calvin cycle is repeated to form a glucose molecule.

• Carbon dioxide (CO2) fixation occurs during Calvin cycle.
• The Clavin cycle processes through three stages namely Carboxylation, Reduction, and Regeneration.
• One molecule of carbon dioxide is fixed in one turn of calvin cycle.
• For the synthesis of one glucose molecule, total 6 atoms of carbon are required in the process.
• Hence, six turns of Calvin cycle are required to produce one molecule of hexose sugar.

Thus, the correct answer is 6.
