How many times must the Calvin cycle be run to generate?
Only one carbon dioxide molecule is incorporated at a time, so the cycle must be completed three times to produce a single three-carbon GA3P molecule, and six times to produce a six-carbon glucose molecule.
How many turns of the Calvin cycle does it take to generate one molecule of the 6 carbon sugar fructose?
six turns Because the carbohydrate molecule has six carbon atoms, it takes six turns of the Calvin cycle to make one carbohydrate molecule (one for each carbon dioxide molecule fixed).
How many glucose molecules are produced for every turn of the Calvin cycle?
Six “turns” of the Calvin cycle use chemical energy from ATP to combine six carbon atoms from six CO2 molecules with 12 “hot hydrogens” from NADPH. The result is one molecule of glucose, C6H12O6.
How many times does the Calvin cycle turn for two glucose?
so, six turns of the cycle are required to fix the glucose molecules containing 6 carbon atoms.
Why is Calvin cycle 6 times?
Because the carbohydrate molecule has six carbon atoms, it takes six turns of the Calvin cycle to make one carbohydrate molecule (one for each carbon dioxide molecule fixed).
Why does Calvin cycle occur 6 times?
Because it takes six carbon molecules to make a glucose, this cycle must be repeated six times to make a single molecule of glucose. To accomplish this equation, five out of six glyceraldehyde-3 phosphate molecules that are created through the Calvin cycle are regenerated to form RuBP molecules.
Why does the Calvin cycle need to turn 6 times?
Because the carbohydrate molecule has six carbon atoms, it takes six turns of the Calvin cycle to make one carbohydrate molecule (one for each carbon dioxide molecule fixed). The remaining G3P molecules regenerate RuBP, which enables the system to prepare for the carbon-fixation step.
How many ATP are required for one turn of the Calvin cycle?
G3P produced by the Calvin cycle is the raw material used to synthesize glucose and other carbohydrates. The Calvin cycle uses 18 ATP and 12 NADPH molecules to produce one glucose molecule.
Why does it take 6 turns of the Calvin cycle to make 1 glucose?
We know, a glucose molecule consist of 6 carbon atoms (i.e. C6H12O6). One turn of Calvin cycle fixes only one CO2 molecule hence for the formation of a glucose molecule SIX TURNS OF CALVIN CYCLE IS REQUIRED.
How many times c3 cycle is repeated?
There are 6 atoms of carbon required for the synthesis of one glucose molecule. Hence, to produce one molecule of hexose sugar, six turns of Calvin cycle are required. Thus, the correct answer is option C.
What is produced in one turn of the Calvin cycle?
One turn of Calvin cycle fixes one molecule of carbon dioxide. There are 6 atoms of carbon required for the synthesis of one glucose molecule.
Why do you need six turns of the Calvin cycle to make one hexose sugar?
TP contains three carbons and a hexose sugar contains six, therefore two molecules of TP are required to make one hexose sugar. This means that six turns of the Calvin cycle are required to produce two molecules of TP which can be used to make one hexose sugar.
