Which physiological effect occurs when a hibernating arctic ground squirrel transitions to shivering thermogenesis?

💡 Explanation

When a hibernating ground squirrel initiates shivering, anaerobic glycolysis occurs locally in muscle tissue because of increased ATP demand exceeding aerobic capacity, leading to lactic acid production and localized pH decrease. Therefore localized pH decrease results, rather than increased UCP1 activity or reduced reliance on BAT which are characteristic of non-shivering thermogenesis.
