Exploring Enzyme Function and Characteristics

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 enzyme specificity, the induced fit model, and the importance of enzymes like lactase in digestion. The video also covers the role of cofactors and the impact of environmental conditions on enzyme activity, concluding with the medical significance of enzymes.
