Refer to the Table Below, Which Contains Data Collected Using

Multiple Choice

Refer to the table below, which contains data collected using the same techniques that Calvin and his colleagues used to determine the pathway of carbon atoms during photosynthesis.In this experiment, the starting material was a synthesized compound that contained carbon-14.This ¹⁴C-labeled compound was supplied to a living culture of algae at time zero.Then, at 5-second intervals, samples of the culture were harvested and extracted.The extracts were subjected to two-dimensional chromatography, and the resulting spots were numbered and measured for radioactivity.A "0" indicates negligible radioactivity, while a "+" indicates measurable radioactivity; the greater the number of "+" symbols, the greater the radioactivity detected. Based on these results, what is the sequence of compounds in the metabolic pathway?

A) 3  5  2  4  1  6
B) 4  6  1  5  3  2
C) 1  4  6  3  5  2
D) 2  3  5  1  6  4
E) 4  1  5  2  6  3
