Explanation:
Detailed explanation-1: -Carbohydrates and lipids both contain carbon (C), hydrogen (H), and oxygen (0); proteins contain these three elements plus one or more from nitrogen (N), sulphur (S) and phosphorous (P).
Detailed explanation-2: -Carbohydrates, proteins, and fats are digested in the intestine, where they are broken down into their basic units: Carbohydrates into sugars. Proteins into amino acids. Fats into fatty acids and glycerol.
Detailed explanation-3: -Each macromolecule is broken down by a specific enzyme. For instance, carbohydrates are broken down by amylase, sucrase, lactase, or maltase. Proteins are broken down by the enzymes pepsin and peptidase, and by hydrochloric acid. Lipids are broken down by lipases.
