Q1. A migrating bird relies on stored biological molecules for long-distance flight. Which molecule provides the maximum energy per unit weight?
Answer: Acylglycerols
Explanation: Acylglycerols (fats) provide the highest energy yield per gram because of their high C-H bond density. Carbohydrates provide less than half that energy.
