Practice objective / multiple choice question 6 from the 2022 Igcse Model Questions Vol1 Biology examination.
A person at rest has a tidal volume of \(0.5\) L and a respiratory rate of \(12\) breaths per minute. During moderate exercise the tidal volume rises to \(1.2\) L and the respiratory rate to \(20\) breaths per minute. The fraction of inhaled oxygen removed from the air is \(5\%\) at rest and \(15\%\) during exercise. Atmospheric air contains \(21\%\) oxygen. Calculate the increase in the volume of oxygen consumed per minute when the person moves from rest to exercise. Give your answer in litres of O₂ per minute, correct to two decimal places.
