Neco Model Questions Vol1 2025 Biology Question 31
Practice objective / multiple choice question 31 from the 2025 Neco Model Questions Vol1 Biology examination.
During a 10‑minute bout of intense exercise a person's oxygen uptake (VO₂) is measured at \(2.5\) L·min⁻¹ and carbon dioxide output (VCO₂) at \(2.0\) L·min⁻¹. Assuming complete aerobic oxidation of glucose \(\text{C}_6\text{H}_{12}\text{O}_6 + 6\,\text{O}_2 \rightarrow 6\,\text{CO}_2 + 6\,\text{H}_2\text{O}\) and that each mole of O₂ yields about \(5.0\) mol of ATP, determine: (a) the total amount of ATP (in moles) produced in the 10‑minute period, and (b) the respiratory quotient (RQ) and what it indicates about the predominant substrate being oxidised.
