Question

The ratio between hydrogen and oxygen in carbohydrate is
A) 5:1
B) 4:3
C) 3:1
D) 2:1

Answer 1

Hint: A carbohydrate is an organic compound such as sugars, starches, celluloses, and gums, which occurs in the living tissues and food items. It is important for nutrition and dietetics because it can be broken down into energy by people or animals for their needs. A carbohydrate is a biomolecule, which contains - carbon, hydrogen, and oxygen atoms. A monosaccharide is the easiest form of carbohydrate. Carbohydrates can be divided into three subtypes: monosaccharides, disaccharides, and polysaccharides.

Complete answer:
Carbohydrates usually have a ratio of two hydrogen molecules for one oxygen molecule, just like water along with the same number of oxygen atoms and carbon atoms. Many molecules that offer energy to living organisms get that energy from some types of carbohydrate, like sugars, starch, or cellulose. The simplest form of carbohydrate is a monosaccharide which is composed of carbon, hydrogen, and oxygen. These are considered the simplest form of sugar. The ratio between hydrogen and oxygen is 2:1. For example, fructose is a monosaccharide with five carbon atoms, ten hydrogens, and five oxygen.

The correct option from the above given statement is option (D) – 2:1.

Note:
The monosaccharide is the simplest sugar. The most generous biomolecules on earth are carbohydrates. The three elements namely carbon, hydrogen, and oxygen present in carbohydrates are in the ratio of 1:2:1 respectively, this is why they are called carbohydrates. In lipids, the components are the same but the ratio is less for oxygen, so it is 1:2: less than one for C:H:O.
