Study Notes
Enzymes
- Catalysts that speed up chemical reactions without being consumed
- Enzymes are biological catalysts
- Catalysts for biochemical reactions
- Cellulase helps animals break down cellulose
- Sucrase breaks down complex carbohydrates to fructose and glucose
- Enzymes help in the digestion of toxic substances
Factors Affecting Enzyme Activity
- pH: Changes in pH alter enzyme shape, affecting function
- Temperature: Increased temperature speeds up reaction rates, but high temperature can denature enzymes
- Substrate concentration: Higher concentration increases reaction rate until saturation point is reached.
- Cofactors: Non-protein molecules that help enzymes
- Inhibitors: Substances that slow down or stop catalysis
Activation Energy
- The minimum energy required to start a chemical reaction
- Enzymes lower activation energy, making reactions faster
Active Site
- The specific region of an enzyme where the substrate binds
- Substrate specificity : Enzymes and substrates fit together like a lock and key
- Induced fit Model : Enzymes subtly change shape when they bind to a substrate, creating a tighter fit.
Enzyme-Substrate Complexes
- Temporary complex formed when an enzyme binds to a substrate.
