Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
How are complex carbohydrates formed and broken down?
A
By dehydration synthesis
B
By Hydrolysis
C
By glycosidic bond
D
By Oligosaccharides
Explanation: 

Detailed explanation-1: -When we eat carbohydrates, our body has to digest them for energy. The process of digestion is called hydrolysis. In hydrolysis, these long sugar chains (polymers) are broken down into the individual sugars (monomers) that make them up. The general formula for hydrolysis is: Polymer + Water ⇌ Monomer + Monomer.

Detailed explanation-2: -Hydrolysis is the break down of a large insoluble molecule, into a smaller, soluble molecule, using water. Carbohydrates are broken down in two stages. Starch in carbohydrates first broken down into maltose, and then maltose is then broken down into lots of smaller simple sugars such as glucose, fructose and galactose.

Detailed explanation-3: -Complex carbohydrates can be broken down into smaller carbohydrate units through a process known as hydrolysis.

Detailed explanation-4: -On hydrolysis, these carbohydrates yield a large number of monosaccharides. Example: Starch, glycogen, and cellulose.

Detailed explanation-5: -Complex carbohydrates contain longer chains of sugar molecules than simple carbohydrates. The body converts these sugar molecules into glucose, which it uses for energy. As complex carbohydrates have longer chains, they take longer to break down and provide more lasting energy in the body than simple carbohydrates.
