How many six-carbon sugar molecules are produced by the Calvin cycle when 18 CO₂ are fixed? A) 3 B) 9 C) 18 D) 36 E) 44

Question

Quizplus · Accepted Answer

The Calvin cycle uses 3 molecules of CO2 to produce one molecule of a six-carbon sugar. Therefore, if 18 molecules of CO2 are fixed, it would produce 18/3 = 6 six-carbon sugar molecules. However, since 6 is not an option, it seems there was a mistake in the transcription of the question or the answer choices. Based on the provided options, the closest correct interpretation aligns with the process of the Calvin cycle, but none of the options accurately reflect the standard output of 6 molecules from 18 CO2 molecules. Given the context, option A (3) is the closest, assuming a typo in the question or misunderstanding in the calculation process.
