Which of the following is a characteristic of carbohydrates?
A) Energy source for animals B) Consists of sugars and sugar polymers C) A structural component in plants D) All of the above are characteristic of carbohydrates
Answer- D) All of the above are characteristic of carbohydrates.
Explanation- Carbohydrates are the primary energy source of animals. they intake carbohydrate as food and that carbohydrate broke down into simple sugars like glucose. Glucose provides ATP which is the main thing to continue the metabolic activity. Excess glucose stored as glycogen in muscles and it provides energy during fasting etc.
whereas carbohydrate has the general structural formula of Cn (H2O)n [n= number of atoms]. Disaccharides like sucrose is composed of two simple sugar glucose and fructose. Starch which is a polysaccharide consists of alpha glucose.
Principal component of plant cell wall is cellulose, which is a carbohydrate (Polysaccharide). Monomer of cellulose is beta glucose. It gives the shape of a plant cell. so, all of the above are characteristic of carbohydrates.
