1. Carbohydrates
2. Fats
3. Vitamins
4. Proteins

Answer 1

Correct Answer - Option 2 : Fats

The correct answer is Fats.

• Fats have the highest gross calorific value.
  • The digestion of fats starts from the small intestine.
  • Bile from the liver makes the solution alkaline and breaks down the big fat globules into smaller ones.
  • Lipase from the pancreas breaks down the fats further in the small intestine.
  • Intestinal juice completes the process of digestion of fats and is absorbed.
  • Fats are found in vegetable oils, animal, fats and other foods like nuts.

• About Carbohydrates:
  • They are sugars and starches and also give us energy.
  • They are found in many foods like cereals, vegetables, etc.
  • The mouth or the buccal cavity is the beginning of carbohydrate digestion.
  • Salivary amylase breaks down the carbohydrates (starch) into sugars with the help of the grinding action by the teeth.
  • Pancreatic amylase digest the further carbohydrates in the small intestine.
• About Vitamins:
  • Vitamins were founded by Funk.
  • Vitamins help to keep the organs healthy, and the systems in good working order.
  • It also helps us to fight germs and therefore prevent disease.
• About Proteins:
  • The chewed and partly digested food enters from the mouth to the stomach.
  • Here the pepsin released by it digests protein present in the food.
  • The hydrochloric acid creates an acidic environment for the action of pepsin.
  • Trypsin released in the small intestine, from the pancreas, digests the proteins which are then absorbed after the action of some intestinal enzymes.
