WebCannon (1932) described the capacity for an animal to regulate its internal environment as the product of a suite of physiological processes, called homeostasis. Homeostatic … WebOne of the most important roles of enzymes is to aid in digestion. Digestion is the process of turning the food we eat into energy. For example, there are enzymes in our saliva, pancreas, intestines and stomach. They break down fats, proteins and carbohydrates. Enzymes use these nutrients for growth and cell repair. Enzymes also help with:

WebIf heat generation exceeds the heat loss, mechanisms such as panting or perspiring increase heat loss. Unlike ectotherms, endotherms can be active and survive at quite low external temperatures, but because they must produce heat continuously, they require high quantities of “fuel” (i.e., food).
