Which circumstance arises when a marmot unexpectedly awakens during the late hibernation phase?

A)Increased vasoconstriction in peripheral tissues
B)Accelerated glycogen synthesis in liver
C)Rapid depletion of brown fat reserves
D)Suppressed activation of uncoupling proteins

💡 Explanation

Waking early, the marmot initiates thermogenesis; the mechanism of Non-shivering thermogenesis rapidly burns brown fat. This occurs because the body attempts to restore normal temperature, therefore limited fat reserves deplete quicker, rather than triggering vasoconstriction which conserves already present heat.
