← Nature & AnimalsWhich physiological response occurs in soaring birds during prolonged flight, impacting their metabolic rate?
A)Increased glycogenolysis in flight muscles
B)Uric acid buildup leading to oxidative stress
C)Ketone body production from lipid metabolism✓
D)Elevated red blood cell concentration
💡 Explanation
During prolonged soaring flight, birds utilize lipid metabolism to minimize weight and efficiently extract energy; lipolysis increases as glycogen stores deplete, leading to ketone body production influencing metabolic rate for extended soaring periods. Therefore ketone bodies result, rather than gluconeogenesis, uric acid increases, or blood cell concentration increases, requiring different metabolic conditions.
