Enzymes: Nature's Factory Workers

The video explains enzymes, proteins that catalyze biochemical reactions by lowering activation energy. Enzymes are highly specific, recognizing substrates like a lock and key. They facilitate reactions by binding substrates at active sites, sometimes causing induced fits. Enzymes can break down or build molecules, with types including hydrolases, lyases, ligases, transferases, isomerases, and oxidoreductases. Enzyme mechanisms may involve covalent linkage or acid-base catalysis, often requiring cofactors or coenzymes. Enzymes are crucial for biological processes, enabling reactions under physiological conditions.

How do enzymes achieve specificity for their substrates?

What are the different categories of enzymes and their functions?
