Thermoregulation and the Coast to Coast
Thermoregulation is the maintenance of a stable body temperature, even under external conditions. In humans, this temperature is about 37 degrees Celsius, although the normal range is from 35.5 to 40 degrees Celsius. Having a range allows for variation in the factors that can impact the body temperature. Some of these factors might include exercise, circadian rhythm, hormone levels, the temperature of the surrounding environment (ambient temperature), and food intake.

Thermoregulation is important, especially in humans, as temperatures above 40 degrees Celsius cause enzymes to denature rapidly. Enzymes have an optimal range for catalysing reactions. Temperatures below this cause for the rate at which reactions occur to decrease, whereas temperatures above this can lead to the denaturing of enzymes and important metabolic reactions unable to occur. Therefore it is essential for enzymes in the body to be functioning.
On the other hand, the lipid bilayer contains many proteins that will only operate if they are free floating on this bilayer. It is only possible for these proteins to float is the lipid bilayer is liquid, and at low temperatures the bilayer may change phase and freeze. These effects can reduce essential cellular functions, which can reduce energy availability. Maintaining a stable body temperature is crucial in environments such as the Coast to Coast, as energy demands are high in order to survive the physical exhaustion…
