Neco Model Questions Vol1 2025 Biology Question 9
Practice objective / multiple choice question 9 from the 2025 Neco Model Questions Vol1 Biology examination.
A cell oxidises glucose (\(\mathrm{C}_{6}\mathrm{H}_{12}\mathrm{O}_{6}\)) and palmitic acid (\(\mathrm{C}_{16}\mathrm{H}_{32}\mathrm{O}_{2}\)). For every 3 molecules of glucose oxidised, 1 molecule of palmitic acid is oxidised. The respiratory quotient (RQ) for a substrate is the ratio of \(\mathrm{CO}_{2}\) produced to \(\mathrm{O}_{2}\) consumed. Given that glucose yields an RQ of 1 and palmitic acid yields an RQ of \(16/23\), calculate the overall RQ for the mixture.
