Exploring Enzymes and Their Industrial Applications

The video explains the role of enzymes in facilitating chemical reactions without being consumed. Enzymes are proteins that speed up reactions and are specific to substrates. They are used in various industries, such as in biological detergents for stain removal and in cheese production with rennet.

What are enzymes primarily made of?

• Carbohydrates

• Proteins

• Nucleic acids

• Lipids
