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: -After consuming sucrose, our body needs to digest it through a process called hydrolysis. During hydrolysis, water is added into the disaccharide to break it apart. The result is the monomers: glucose and fructose. Polysaccharides are composed of many sugars.

Detailed explanation-2: -When you eat carbs, your body breaks them down into simple sugars, which are absorbed into the bloodstream. As the sugar level rises in your body, the pancreas releases a hormone called insulin. Insulin is needed to move sugar from the blood into the cells, where the sugar can be used as a source of energy.

Detailed explanation-3: -Complex carbohydrates are made up of sugar molecules that are strung together in long, complex chains. Complex carbohydrates are found in foods such as peas, beans, whole grains, and vegetables. Both simple and complex carbohydrates are turned to glucose (blood sugar) in the body and are used as energy.

Detailed explanation-4: -Digestion of Carbohydrates Digestion of starches into glucose molecules starts in the mouth, but primarily takes place in the small intestine by the action of specific enzymes secreted from the pancreas (e.g. -amylase and -glucosidase).

Detailed explanation-5: -The digestion of carbohydrates by enzyme catalysed hydrolysis begins in your mouth and continues in your stomach and small intestine. The final product of the digestion of carbohydrates are monosaccharides such as glucose and fructose. Glucose is used by your cells during respiration to produce energy.
