No, oxygen is not made during the Calvin cycle. The Calvin cycle is part of the light-independent reactions in photosynthesis and is responsible for converting carbon dioxide into glucose, not producing oxygen. Oxygen is produced during the light-dependent reactions of photosynthesis.
The Calvin cycle goes through a full cycle three times to produce one molecule of glyceraldehyde-3-phosphate (PGAL).
No, photolysis does not occur in the Calvin cycle. Photolysis is the process of breaking down water molecules in the light-dependent reactions of photosynthesis to produce oxygen, while the Calvin cycle is the series of reactions that occur in the stroma of the chloroplast to fix carbon dioxide and produce sugars.
In the Calvin-Benson cycle, ATP can donate a phosphate group to regenerate ribulose-1,5-bisphosphate (RuBP) in the regeneration phase of the cycle. This process is vital for the continuation of carbon fixation and the production of carbohydrates.
Yes, ribulose is a pentose sugar. It is a five-carbon sugar that is involved in the Calvin cycle of photosynthesis as part of the Calvin-Benson cycle.
Carbon dioxide
The reactant in the Calvin cycle is carbon dioxide (CO2) from the atmosphere. This carbon dioxide is fixed and converted into organic molecules, such as glucose, through a series of enzymatic reactions in the Calvin cycle.
ATP, NADPH, and CO2
Carbon dioxide is the reactant used in the Calvin cycle. It is combined with ribulose-1,5-bisphosphate (RuBP) by the enzyme Rubisco to initiate the process of carbon fixation and ultimately produce glucose.
