How Does Digestive enzymes | Physiology | Biology | FuseSchool Work?

Digestive enzymes are like tiny helpers that make it easier for your body to eat and grow.

Imagine you're eating a big, tough piece of meat, it's hard to chew and swallow. That’s where digestive enzymes come in! They’re special proteins found in your mouth, stomach, and intestines. These tiny helpers work like scissors or magic erasers that cut up food into smaller pieces so your body can use them.

How Digestive Enzymes Work

Think of your mouth as a kitchen. When you chew, your teeth are like knives, and saliva is like the first helper in the kitchen, it has an enzyme called amylase, which starts turning carbohydrates (like bread or pasta) into simple sugars.

In your stomach, another enzyme called pepsin helps break down proteins from meat or eggs. It’s like a special tool that turns big chunks of protein into smaller parts.

Then in the intestines, more enzymes, like lactase, which helps you digest milk, finish the job so your body can absorb all the good stuff and turn it into energy for playing and growing!
