Practice practical question 4 from the 2023 Ijmb Model Questions Vol1 Biology examination. This question covers Respiration .
A closed respirometer was used to measure the rate of aerobic respiration of a suspension of baker's yeast (Saccharomyces cerevisiae) at three different temperatures. The volume of oxygen evolved was recorded over a fixed period of 5 min as shown in the table below. | Temperature (°C) | O₂ evolved in 5 min (mL) | |------------------|--------------------------| | 20 | 12.0 | | 30 | 18.5 | | 40 | 28.0 | Assume the gas is collected at 25 °C and 1 atm and that the volume recorded is directly proportional to the amount of O₂ produced.
