The ultimate substance to which the carbohydrates are degraded is

Correct answer: (b) glucose

Explanation

Dietary carbohydrates are ultimately broken down (digested) into the monosaccharide glucose, which is absorbed into the blood.

Glucose (C6H12O6) is the simplest carbohydrate and the body's instant energy source.

Maltose is a disaccharide and an intermediate, while glycerol and amino acids come from fats and proteins, not carbohydrates.
