Q. How many PGAL are produced by glycolysis of 3 molecules of glucose? How many ATP are released by respiration of these PGAL till formation of C$O_{2}$ and $H_{2}$O?

A) 4 PGAL- 80 ATP
B) 6 PGAL-160ATP
C) 4 PGAL-40ATP
D) 6 PGAL-120ATP
Explanation

Glycolysis of one molecule of glucose produces 2PGAL, thus of three molecules will produce 6PGAL. Respiration of one molecule of glucose or 2PGAL produces 38ATP molecules, thus, of 6PGAL will produce 114 ATP molecules. Out of the given option, 120 ATP is the nearest correct answer.
