← Nature & AnimalsWhich outcome sharply escalates in hibernating mammals when cytoplasmic uncoupling diminishes within their brown adipose tissue?
A)Decreased substrate level phosphorylation
B)System-wide cellular ATP production✓
C)Pronounced and rapid body rewarming
D)Depressed oxygen consumption rate
💡 Explanation
Elevated ATP production follows diminished uncoupling because oxidative phosphorylation becomes the primarily proton gradient dissipater rather than thermogenin; therefore ATP surges systemically, rather than heat generation; different hormonal triggers prevent this while hibernation occurs.
