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.
