In the Cellular Respiration laboratory, you experimented with peas and saw how the rate of oxygen consumption during cellular respiration varied with temperature. In that lab, you experimented with peas to see how the rate of oxygen consumption during cellular respiration increased with temperature.
In animals, an increase in cellular respiration triggers homeostatic mechanisms that increase both breathing and heart rate, resulting in more oxygen being available to cells.
In the second part of this lab, you will study the relationship between temperature and metabolic activity in an ectothermic animal. An ectotherm is an animal whose body temperature is much the same as its surroundings, such as a frog, a cricket, or a snake.
To learn more about how ectothermic behavior relates to temperature, take a side trip to Thermoregulation.
