Enzyme Functions and Classifications

The video tutorial discusses different classes of enzymes and their functions using a mnemonic 'over the hills' to aid memory. It covers oxidoreductases, transferases, hydrolases, isomerases, lyases, ligases, and synthetases, providing examples and explaining their roles in biological processes. The tutorial emphasizes the importance of these enzymes in cellular functions and offers a simple way to remember them.
