← Nature & AnimalsWhich risk increases when brown adipose tissue respiration declines during hibernation?
A)Inadequate shivering thermogenesis initiation✓
B)Reduced efficiency of oxygen diffusion
C)Increased reliance on muscular contraction
D)Compromised non-shivering thermogenesis capacity
💡 Explanation
Insufficient brown fat respiration impairs non-shivering thermogenesis, because proton leak across the inner mitochondrial membrane (thermogenin) is reduced; therefore shivering can't initiate quickly enough, rather than diffusion failing because temperature is already too low.
