Where do the enzymatic reactions of the Calvin cycle takes place?
(a)
An enzyme that fixes CO2 from atmosphere to convert it to complex macromolecule glucose is called (a)
How many CO2 molecules are needed in Calvin cycle to produce one net G3P molecule?
(a)
Which of the following is NOT true about photorespiration?
Photorespiration occurs on hot dry days.
When the concentration of O2 is high, Calvin cycle proceeds as usual.
When the concentration of CO2 is low, photorespiration occurs.
It is called photorespiration because it produces CO2 & H2O.
