Question

What percentage of ATP energy is produced when 2 moles of glucose react in glycolysis? (7.3 kcal/mole ATP)

What percentage of ATP energy is produced when 2 moles of glucose are oxidized into acetyl CoA? (7.3 kcal/mole ATP) Express your answer to two significant figures.

What percentage of ATP energy is produced when 2 moles of glucose react in the citric acid cycle? (7.3 kcal/mole ATP)

What percentage of ATP energy is produced when 2 moles of glucose are completely oxidized to CO2 and H2O? (7.3 kcal/mole ATP)

Explanation / Answer

During glycolysis 2 mole of ATP is produced from 1 molecule of glucose giving 7.3*2 so from 2 molecule of glucose give 4 ATP =29.2kcal of enrgy

so the percentage pf ATP energy from 2 molecule of glucose can be calculated from taking the ration og glucose to ATP= 14.6/720*2 =29.2/1440

0.020= 20% of ATP energy is produced.

So from 2 glucose 4 pyruvate produce thus giving 4 ATP

thus total 8 ATP produced from 2 mol of glucose = 7.3*8 =58.4

percentage of ATP = 58.4/1440 =0.040=40%
