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.
