Figure 5 again-Yes, the relationship between Acidification Power and Specific Oxygen Uptake rate one more time. Question 7 options: Figure 5 is a wonderful resource. Because the correlation between AP and Specific Oxygen Uptake Rate is so tight (p = <0.001) we can use the equation of the line to determine Specific Oxygen Uptake Rate and not invest in the time, equipment and financial investment required to actually calculate the specific O2 uptake. Figure 5 is a wonderful resource. Because the correlation between AP and Specific CO2 Uptake Rate is so tight (p = <0.001) we can use the equation of the line to determine Specific Oxygen Uptake Rate and not invest in the time, equipment and financial investment required to actually calculate the specific CO2 uptake. "For control of fermentation, knowledge of the specific oxygen uptake rate of yeast can be useful". Oxygen is required for yeast cells to be viable. With an AP value of 3, using the equation of the line we can predict the Specific Oxygen Uptake rate to be about 0.3 mg oxygen/min/g.dry wt. With an AP value of 3, using the equation of the line, the calculated Specific Oxygen Uptake Rate is 0.3999 mg
