With reference to three Calvin cycles, which of the given options is correct for the following question? I. How many gross PGAL molecules are produces? II. Total, how many ATP molecules are required for synthesis of PGAL molecules? II. Total, how many NADPH molecules are required for the synthesis of obtained PGAL molecules?
View answer and explanation
Correct option: B
I-6 PGAL, II-6 ATP, III-6 NADPH
The correct answer is B (I-6 PGAL, II-6 ATP, III-6 NADPH) because three Calvin cycles produce 6 gross PGAL, requiring 6 ATP and 6 NADPH.
