Which process minimizes energy reserves expenditure during bear hibernation?

A)Suppressed metabolic rate and hypothermia
B)Elevated glycogenolysis and lipolysis
C)Increased muscle tone and shivering
D)Enhanced erythrocyte production and angiogenesis

💡 Explanation

Entering periods of hypothermia lowers the internal body temperature which suppresses metabolic enzyme activity; because less activity occurs to maintain homeostasis, therefore energy savings during hibernation are substantial rather than expending reserves on basal metabolic processes.
