Final answer:
Endothermic metabolisms typically are homeothermic, meaning they maintain a constant body temperature for efficient metabolic processes.
Step-by-step explanation:
Endothermic metabolisms typically are homeothermic. Homeothermy refers to the ability of an organism to maintain a constant body temperature in order to carry out metabolic processes efficiently. This is achieved through various mechanisms such as hibernation, aestivation, or migration in response to extreme temperatures. Maintaining a constant body temperature allows for optimal enzyme function and efficient metabolic pathways.
