To identify: The number of CO2, ATP, and NADPH molecules required in the Calvin cycle to synthesize one glucose molecule.
Introduction:
Carbon dioxide diffuses into the chloroplast stroma, where sugar is created via the Calvin cycle, from the inside of a leaf through pores called stomata. Since light does not play a direct role in these processes, they are also known as light-independent reactions.
Carbon dioxide is converted into three-carbon sugars through the Calvin cycle, which involves the fixing (or incorporation) of carbon into organic molecules. The ATP (adenosine triphosphate) and NADPH (nicotinamide adenine dinucleotide phosphate) produced in photosynthesis power and sustain this procedure. In contrast to the light reactions, which occur in the thylakoid membrane, the reactions of the Calvin cycle occur in the stroma.
