    Purpose Thermoregulation is the ability of an organism to keep its body temperature within certain boundaries‚ even when the surrounding temperature varies and is of higher or lower temperature than what is normal. The purpose of thermoregulation is to balance thermal inputs and thermal losses in the body so as to maintain a relatively constant core temperature of approximately 36.7 degrees celsius. If this was unable to take place the body may not be able to functions properly and it could result

    How does temperature affect the rate of reaction for Lipase? As the temperature increases‚ so will the rate of enzyme reaction. However‚ as the temperature exceeds the optimum the rate of reaction will decrease. I predict that at temperatures above 70°C the enzyme lipase will become denatured and at temperatures below 10°C the enzyme will become inactive. Since lipase operates within the human body I’d also predict that its optimum temperature would be around human body temperature which is approximately
