Biochemists measured the rate of glucose consumption (in $\text{mM/min}$ ) by a newly isolated bacterial strain across 3 temperature treatments ( $25^\circ\text{C}$ , $35^\circ\text{C}$ , and $45^\circ\text{C}$ ). Each temperature condition was evaluated in 3 separate trials. The results are recorded in the table below:

Temperature ( $^\circ\text{C}$ )	Trial 1 ( $\text{mM/min}$ )	Trial 2 ( $\text{mM/min}$ )	Trial 3 ( $\text{mM/min}$ )
$25$	$1.2$	$1.5$	$1.8$
$35$	$4.0$	$4.6$	$4.6$
$45$	$2.1$	$2.5$	$2.0$

Based on the data provided, what is the average rate of glucose consumption, in $\text{mM/min}$ , for the $35^\circ\text{C}$ treatment across the 3 trials?

Answer: 4.4 mM/min

Answer

The average rate of glucose consumption at

35^\circ\text{C}

across the 3 trials is

4.4\text{ mM/min}

To find the average glucose consumption rate at

35^\circ\text{C}

, locate the row for

35^\circ\text{C}

in the table and sum the values across the 3 trials (

4.0 + 4.6 + 4.6 = 13.2\text{ mM/min}

). Then divide by the number of trials (

3

) to get

\frac{13.2}{3} = 4.4\text{ mM/min}

Step-by-Step Solution

Extract data points for the

35^\circ\text{C}

row

Trial 1 =

4.0\text{ mM/min}

, Trial 2 =

4.6\text{ mM/min}

, Trial 3 =

4.6\text{ mM/min}

The question specifically asks for the average at

35^\circ\text{C}

Calculate the sum of the trial values

4.0 + 4.6 + 4.6 = 13.2\text{ mM/min}

Calculating an average requires finding the total sum of all trial measurements first.

Divide the sum by the total number of trials

\frac{13.2}{3} = 4.4\text{ mM/min}

Dividing the sum by

3

calculates the arithmetic mean across the 3 trials.
