Question:
Recall that the complete oxidation of a mole of glucose releases 686 kcal of energy (
ΔG=- 686 kcal/mol). The phosphorylation of ADP to form ATP stores approximately 7.3 kcal per mole of ATP. What is the approximate efficiency of cellular respiration for a "mutant" organism that produces only 29 moles of ATP for every mole of glucose oxidized, rather than the usual 36-38 moles of ATP?
A) 0.4%
B) 25%
C) 30%
D) 40%
E) 60%
Answer:
C) 30%
