Solution
The correct option is C Carbohydrates
Lipids give maximum energy in metabolic processes. Lipids gets converted into fatty acids on reduction. Therefore, the energy content of fat is over twice that of glycogen and proteins. Both glycogen and proteins are hydrophilic, and bind water. The result is that the stored glycogen and protein have a much lower energy density than the hydrophobic lipids. While fats have 9 calories per gram of energy, carbohydrates and proteins have only 1−4 calories per gram.
