Study Notes
- Enzymes are often compared to Pac-Man in terms of their function, as enzymes, like Pac-Man, have a specific active site where substrates bind, similar to Pac-Man eating pellets.
- Enzymes can speed up reactions by binding to specific substrates and breaking them down into products, playing a crucial role in making life processes efficient.
- An excellent real-life example is the enzyme lactase, which breaks down lactose into smaller parts that the body can digest effectively, essential for lactose intolerant individuals who lack sufficient lactase enzymes.
- Enzymes act as catalysts in reactions, meaning they remain unchanged and can be used repeatedly in reactions to speed up processes.
- The digestive system utilizes various enzymes like lipase for breaking down lipids, amylase for breaking down starches, and protease for breaking down proteins.
- Enzymes require specific ideal conditions to function optimally, such as pH and temperature, and deviations from these conditions can denature the enzyme, causing it to lose its shape and function.
- Enzymes play a vital role in regulating many bodily processes, and disruptions in enzyme production or function can lead to various diseases, highlighting the significance of enzymes in the body.
