What makes the Calvin cycle a cycle?
The Calvin cycle is a cycle because it begins and ends with the same molecule, ribulose-1,5-bisphosphate (RuBP). This molecule is regenerated at the end of the cycle after it undergoes a series of reactions that produce sugars used by the plant for energy.
Which molecule is a reactant in the first step and final product in the fourth step of the Calvin Benson cycle?
RuBP
Which substrate is regenerated after one cycle of the Kreb's cycle?
Oxaloacetate is the substrate that is regenerated after one cycle of the Krebs cycle. It combines with acetyl-CoA to continue the cycle.
How many times must the Calvin cycle turn for the plant cell to be able to produce molecule of glucose?
six
Why is the Calvin cycle called a cycle?
The Calvin cycle is called a cycle because it is a series of biochemical reactions that regenerate the starting molecule. The cycle starts with a 5-carbon molecule (RuBP) and ends with the regeneration of RuBP, allowing the process to continue in a cyclic manner.
What makes the Calvin cycle a cycle?
The Calvin cycle is a cycle because it begins and ends with the same molecule, ribulose-1,5-bisphosphate (RuBP). This molecule is regenerated at the end of the cycle after it undergoes a series of reactions that produce sugars used by the plant for energy.
What molecule is reduced in the Calvin Cycle?
In the Calvin Cycle, the molecule that is reduced is carbon dioxide (CO2).
Which molecule is a reactant in the first step and final product in the fourth step of the Calvin Benson cycle?
RuBP
What are the similarities between the Krebs Cycle and the Calvin cycle?
Similarity: They are both cycles, therefore both have a reactant that s regenerated. In the Krebs Cycle, oxaloacetate is regenerated. In the Calvin cycle, RuBP is regenerated (ribulose 1, 5-bisphosphate). Difference: Glucose is completely broken down in the Krebs Cycle to carbon dioxide, which in the Calvin Cycle, glucose is made as a product.
How many turns of the Calvin cycle are required to produce a molecule of glucose?
Six turns of the Calvin cycle are required to produce a molecule of glucose.
How many turns of the Calvin Cycle are necessary for one G3P molecule to exit?
One G3P molecule exits the Calvin Cycle after three turns.
What is the molecule that is regenerated with every turn of the Krebs cycle?
Each turn of the Kreb's cycle must regenerate oxaloacetate.
How many repeats of the Calvin Cycle are required to produce one glucose molecule?
Two repeats of the Calvin Cycle are required to produce one glucose molecule.
How many turns of the Calvin Cycle are required to produce one glucose molecule?
Six turns of the Calvin Cycle are required to produce one glucose molecule.
How many turns of the Calvin Cycle are required to produce one molecule of glucose?
Six turns of the Calvin Cycle are required to produce one molecule of glucose.
How many times does the Calvin cycle turn to make 1 molecule of glucose C6H12O60?
The Calvin cycle needs to turn six times to produce one molecule of glucose (C6H12O6) because glucose is a six-carbon molecule. Each turn of the Calvin cycle incorporates one CO2 molecule into a three-carbon compound, which after six turns, is rearranged and combined to form a glucose molecule.
What molecule is fixed during the Calvin cycle to produce sugars?
During the Calvin cycle, carbon dioxide (CO2) is fixed to produce sugars.
