Which physiological impact results when a hibernating ground squirrel's brown adipose tissue mitochondrial uncoupling decreases?

💡 Explanation

When mitochondrial uncoupling decreases, heat production efficiency in brown fat decreases because proton gradient dissipation for ATP synthesis declines, impairing non-shivering thermogenesis during arousal from hibernation leading to reduced body temperature regulation. Therefore temperature decrease results rather than increased shivering, higher rates, or immune depression, which depend on alternative metabolic or immune conditions.
