BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Carbohydrates are made of Nitrogen, Carbon and Hydrogen. Ans-False. Explanation-Carbohydrates are made of Oxygen, Carbon and Hydrogen.

Detailed explanation-2: -Some carbohydrates contain the elements, nitrogen and sulphur. One of the carbon atoms forms a carbonyl (aldehyde or ketone) group whilst the other carbon atoms exhibit hydroxyl groups.

Detailed explanation-3: -Since both the functional groups are attached to the a-carbon so they are called a-amino acids. So, nitrogen is only present in proteins and not in carbohydrates and lipids.

Detailed explanation-4: -Carbohydrates are the biomolecules containing carbon, hydrogen, and oxygen respectively. They are also called hydrates of carbon.

Detailed explanation-5: -The chemical structures of carbohydrates contain carbon, hydrogen, and oxygen atoms. Two basic compounds make up carbohydrates: Aldehydes, which are double-bonded carbon and oxygen atoms, plus a hydrogen atom, and ketones, which are double-bonded carbon and oxygen atoms, plus two additional carbon atoms.
