NEET BIOLOGY

Detailed explanation-1: -Glucose, a 6-carbon sugar, is a simple carbohydrate or “mono-saccharide.” Sugar is a source of quick energy for the body because it is easily metabolized (broken down).

Detailed explanation-2: -Carbohydrates are the body’s main source of quick energy because very little energy is required to break them down. There are three classes of carbohydrates: monosaccharides, disaccharides, and polysaccharides.

Detailed explanation-3: -Carbon compounds have major involvement in the formation of biomolecules. They covalently bind with other elements to form several other compounds.

Detailed explanation-4: -Explanation: There are four classes of biological molecules: fats, carbohydrates, proteins, and nucleic acids. Of these, fats produce the most energy per gram at a whopping nine calories per gram.

Detailed explanation-5: -Carbohydrates closer to exercise are best as they can provide immediate glucose, versus fats which take longer to metabolize.
