How digestive enzymes work – Breakdown of starch & fats
Enzymes play a crucial role in digesting our food. They ensure that the nutrient particles in our food are broken down. In this video, you'll learn about an experiment that demonstrates how enzymes work in general. Then we'll take a closer look at the breakdown of starches and fats. You'll see where and by which enzymes starches and fats are broken down in your digestive system, and what products are produced in the process. You can easily replicate one of the starch breakdown experiments at home!

IN THIS VIDEO WE SHOW:
▸What is digestion?
▸Digestive Enzymes – Functions
▸Digestive Enzymes – Effects
▸Digestive Enzymes – Experiments
Let's start with a simple experiment to demonstrate the effects of enzymes. First, pour one milliliter of a diluted hydrogen peroxide solution into a test tube. Then, add fresh potato juice, seal the test tube, and shake it gently.
You will observe small bubbles and foaming. This indicates that a gas has been produced. If you now hold a glowing wooden splint in the open test tube, it will ignite. This test shows you that the gas produced is oxygen. The potato juice has therefore converted or broken down the hydrogen peroxide in some way, producing oxygen.
