Which metabolic consequence ensures survival when groundhog heart rate slows exceedingly during hibernation?

💡 Explanation

During hibernation, low heart rate limits glucose delivery so ketone bodies are created via beta-oxidation and cross the blood-brain barrier because they can be readily converted to acetyl-CoA to generate brain ATP. Therefore ketone bodies fuel neural activity over anaerobic respiration, increased stores, or contractions which require other fueling pathways.
