Enzymes (Updated)

The video uses a Pac-Man analogy to explain enzymes, highlighting their role in speeding up reactions by binding substrates at their active sites. It discusses the enzyme lactase, which breaks down lactose, and the condition of lactose intolerance. Enzymes are catalysts that can be reused, and they often work with cofactors and coenzymes. The video also covers how enzymes have ideal conditions for activity, such as specific pH and temperature ranges, and how deviations can lead to denaturation, rendering them inactive.
