Based on the fact that one mole of any gas at standard temperature and pressure occupies 22.4liters and contains 6.024 x 1023 molecules, the following equation can be used to calculate thenumber of oxygen molecules consumed per minute:(total ml O2 consumed) X (1 liter) x (1 mole) x (6.024 x 10²³ molecules) = molecules O₂ consumed(total time of experiment) (1000 ml) (22.4 liter)(1 mole)minuteUse this equation, and your data, to calculate the rate of O₂ consumption during your experiment,in molecules/minute, at 40 °C.

The metabolic process by which cells release energy from food molecules and generate the energy required to sustain life is known as cellular respiration. Aerobic respiration occurs in the mitochondria of eukaryotic cells when there is sufficient oxygen for the cell to function. All organisms require cellular respiration in order to survive. This is due to the fact that a cell needs ATP conversion before it can utilize food-derived energy. In order to produce ATP, aerobic respiration requires glucose and oxygen.Total time in minutes = 110 Total ml of O2 consumed = 0.34 To calculate the molecules of O2 consumed per minute, (total O2 consumed) x (1 liter) x (1mole) x (6.024 x 1023molecules) = molecules O2 consumed (Total time of experiment) (1000ml) (22.4 liter) (1 mole) minute 0.34 x 1 x 1 x 6.024 x 1023 = molecules O2 consumed 110 1000 22.4 minute molecules of O2 is consumed per minute= 0.34/110 x 6.024x1023/22400 =3.1x0.27x1017 =8.37x1016
