Solution
The correct options are
A Carbohydrates
C Proteins
D Lipids
Carbohydrates, lipids, and proteins are the major constituents of foods. These nutrients are digested to form glucose, fatty acids and amino acids respectively. Glucose is the major source for energy production. But if glucose is not available then fatty acids and amino acids can also be converted into acetyl-co-A and energy is obtained by the complete oxidation of acetyl-co-A by the process of Kreb's cycle in the mitochondria.
Water is essential for the body. But it cannot be used as a raw material to produce energy by respiration.
