Which metabolic outcome allows hibernating mammals to survive prolonged starvation?

💡 Explanation

Ketone body catabolism spares glucose; therefore, increased reliance on ketone bodies sustains cerebral function during hibernation because energy is derived from stored fat rather than glycogen depletion, rather than proteins, which would be fatal.

• During bird migration over large bodies of water, which outcome commonly occurs when a storm suddenly disrupts the flock's cohesion?
• Which scenario occurs when avian wing loading nears a critical threshold?
• Which outcome occurs when buoyancy control fails during vertical ascents?
• Which outcome limits successful arousal from hibernation during periods of frequent environmental temperature fluctuations?
• Which outcome occurs when prolonged flooding occludes plant stomata?
• Which outcome occurs when a marine mammal rapidly ascends from deep dives to sea level?
