Question

Which of the following does not require enzymatic digestion?

  

proteins

   

starch

   

calcium

   

fats

Answer 1

Digestion is the process that leads to the breakdown of complex molecules into the simpler molecules.

The digestion occurs in the different parts of the body like in the mouth, stomach, small intestine, and large intestine.

Protein, fats, and carbohydrates are present in the food that is digested throughout the body by the process of digestion with the help of different enzymes.

Like protein is digested in the stomach with the help of pepsin enzyme and in the stomach with the help of trypsin and chymotrypsin enzymes.

Carbohydrate digestion gets started in the buccal cavity where maltose present in the food is digested with the help of maltase.

Sucrase, Amylase, Lactase are the enzymes that help in the digestion of carbohydrates Sucrose, Starch, and Lactose respectively.

Lipases are another class of enzyme that helps in the digestion of fats and convert them into fatty acid and glycerol with the help of pancreatic lipase in the intestine, gastric lipase in the stomach.

So, the protein, fats, and carbohydrate need enzymatic digestion because they are present as the larger molecule.

The vitamins and minerals are already present in the minute quantity so their digestion does not need an enzyme. Calcium is the vitamin and their digestion does not need an enzyme they are just absorbed in the different parts of the body like around the bones and make them strong. They are absorbed in the small intestine and the lining of the small intestine is made by them.

Hence, the correct answer to this question is Calcium.
