Examine the results of an experiment above discussing how temperature affects cellular respiration. Identify the temperature at which oxygen levels would be predictably lowest and explain why.

Option D

Explanation:

Options for the given questions are

A) 4 °C because this is where the glucose is in its most solid form, and oxygen is lost at its greatest rate at this temperature.

B) 30 °C because this is the average temperature for yeasts outside of the laboratory, and oxygen saturation is highest at mid-range temperatures.

C) 30 °C because this is where glucose is converted more easily into starches, and oxygen is consumed during cellular respiration.

D) 50 °C because this is the optimal temperature for enzymes responsible for cellular respiration, and oxygen is consumed during cellular respiration.

Solution-

As we are aware of this fact that dissolution of oxygen reduces with increase in the temperature of water. The warmer the water body is, the lesser will be the amount of oxygen. However, as the pressure increases the oxygen dissolution increases.

Now at 50 degree Celsius, the least oxygen will be dissolved. While on the other hand the oxygen content starts depleting because of its consumption by aquatic animals.

Hence, Option D is correct
