Which food component gets broken down into fatty acids and glycerol?

  1. Carbohydrates

  2. Fats

  3. Proteins

  4. Bile juices
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The nutrients which we intake are not directly absorbed by blood. They need to be broken down into simpler forms so that they can be used by the human body. Carbohydrates break down into glucose, proteins into amino acids and fats into fatty acids and glycerol. Bile juice is an example of a digestive juice.

Multiple choice

What is the end product of proteins in the human body?

  1. Fatty acid

  2. Amino acid

  3. Glucose

  4. Glycerol
