← Nature & AnimalsWhich mechanism causes oxygen depletion in muscle tissue of an arctic fox during intense shivering?
A)Increased ATP demand during thermogenesis✓
B)Arteriovenous anastomosis shunts blood flow
C)Increased myoglobin production restricts flow
D)Reduced capillary density inhibits diffusion
💡 Explanation
During intense shivering, skeletal muscles rapidly contract to generate heat, increasing ATP demand through oxidative phosphorylation, consuming large amounts of oxygen which depletes reserves within muscle tissue. Therefore ATP demand results in depletion, rather than other options dependent on altered blood flow or muscle adaptations.
