A muscle cell metabolises \(2.0\) g of glucose anaerobically to lactate and the same amount aerobically to CO₂ and H₂O. Each mole of glucose yields 2 ATP anaerobically and 30 ATP aerobically. (a) Calculate the difference in the total number of ATP molecules produced between the two pathways for the given mass of glucose. (b) Express the percentage increase in ATP yield when aerobic respiration is used.

Answer Options
