Temperature is a key factor that needs to be controlled; the human body maintains a core temperature of around 37.5 °C; A stable core temperature is vital for enzyme activity. Lower temperatures reduce the kinetic energy available for molecules and slow down chemical reactions
Which of the following happens if body temperature rises above normal? a. circulation in the skin decreases b. blood flow to the skin increases c. evaporative cooling stops d. sweat glands activity decreases
The human body regulates body temperature through a process called thermoregulation, in which the body can maintain its temperature within certain boundaries, even when the surrounding temperature is very different.
The human body maintains the temperature at which enzymes work best, around 37°C. If body temperature increases over this temperature, enzymes will denature and become less effective at catalysing reactions such as respiration.
Homeostasis is the maintenance of a constant internal environment. Regulating body temperature, blood glucose level and water content are all examples of homeostasis.
The core temperature of the body remains steady at around 36.5–37.5 °C (or 97.7–99.5 °F). In the process of ATP production by cells throughout the body, approximately 60 percent of the energy produced is in the form of heat used to maintain body temperature.
Animals must be able to maintain homeostasis—the ability to maintain dynamic equilibrium around a set point—while also being able to respond to changing conditions. For example, as an endotherm, your body temperature remains fairly constant around 37 C or 98.6 F.
