Respiration rates are measured by the amount of oxygen per gram of tissue per hour. In a series of experiments, it was determined that a warm-blooded mouse requires 2
5 milliliters of O2 per gram of tissue per hour, whereas a cold-blooded crayfish requires 0.047 milliliter of O2 per gram of tissue per hour. Why is there such a dramatic difference in respiration rates between these animals?
Warm-blooded animals require more energy to maintain their higher body temperature and greater metabolic rate, and energy production is directly proportional to oxygen utilization by the ETC.
