Answer:
Fat stores twice as much energy than carbs at the same mass based on their structure due to the higher energy content per gram in fats compared to carbohydrates. Fats are more energy-dense because they have a higher proportion of carbon-hydrogen bonds, which store more energy compared to the oxygen-hydrogen bonds found in carbohydrates. This structural difference allows fats to yield around 9 calories per gram, while carbohydrates provide about 4 calories per gram. Therefore, fats can store more energy in the form of triglycerides, making them an efficient long-term energy storage molecule in the body.
