Which outcome occurs when a hibernating arctic ground squirrel experiences rapid vasodilation within its brown adipose tissue?

A)Accelerated ATP production in mitochondria
B)Reduced core body temperature stability
C)Increased reliance on white fat catabolism
D)Diminished uncoupling protein-1 activation

💡 Explanation

When rapid vasodilation occurs in brown adipose tissue, heat dissipation increases because increased blood flow overwhelms the shivering heat production mechanism, reducing core body temperature regulation. Therefore lowered core temperature stability results, rather than enhanced ATP synthesis or altered fat metabolism which depend on hormonal regulation and enzymatic processes.
