Which risk increases when brown adipose tissue respiration declines during hibernation?

💡 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.
