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. 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.
