NEET BIOLOGY

Detailed explanation-1: -Polysaccharides are long chains of monosaccharides linked by glycosidic bonds . Three important polysaccharides, starch, glycogen, and cellulose, are composed of glucose. Starch and glycogen serve as short-term energy stores in plants and animals, respectively.

Detailed explanation-2: -Carbohydrates are composed of carbon, hydrogen, and oxygen atoms and are polyhydroxy aldehydes and ketones. Examples of carbohydrates are starch, fibers, sugar, and cellulose.

Detailed explanation-3: -Monosaccharides. Monosaccharides include glucose, galactose and fructose-all commonly found in food. Monosaccharides are single sugar molecules that are the building blocks for all other sugars and carbohydrates.

Detailed explanation-4: -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). Larger, more “complex carbohydrates” are made by stringing together chains of glucose subunits into di-saccharides, tri-saccharides, poly-saccharides.

Detailed explanation-5: -The carbohydrates are the compounds which provide energy to living cells. They are compounds of carbon, hydrogen and oxygen with a ratio of two hydrogens for every oxygen atom. The carbohydrates we use as foods have their origin in the photosynthesis of plants. They take the form of sugars, starches, and cellulose.
