BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Roughage is the fibrous matter in food. It cannot be digested by human digestive system. It is mainly made of indigestible carbohydrate called ‘cellulose’, which is present in plant cell walls.

Detailed explanation-2: -Fiber is a type of carbohydrate that the body can’t digest. Though most carbohydrates are broken down into sugar molecules called glucose, fiber cannot be broken down into sugar molecules, and instead it passes through the body undigested.

Detailed explanation-3: -The more indigestible carbohydrates (oligosaccharides, dietary fibre and resistant starch) provide little energy but they still have important effects on our health.

Detailed explanation-4: -Roughage is an indigestible portion of the food. It largely consists of cellulose of the plants.

Detailed explanation-5: -Starch and glycogen are digestible. The dietary fiber cellulose is indigestible-a complex carbohydrate for which our digestive system has no enzymes.
