Study Notes
Enzyme Catalysis
- The energy that must be overcome to reach the transition state in a reaction is known as the activation energy.
Enzyme-Substrate Interaction
- The induced fit model describes the interaction between an enzyme and its substrate, where the active site undergoes a conformational change to accommodate the substrate.
Enzyme Variations
- Enzymes with the same catalytic activity but different amino acid sequences are known as isoenzymes.
Enzyme Optimum Conditions
- An enzyme exhibits maximum catalytic activity at the optimal pH.
- An enzyme exhibits maximum catalytic activity at the optimal temperature.
Chemical Reactions
- The reactant in an enzyme-catalyzed reaction is known as the substrate.
- Spontaneous reactions can occur without the input of external energy.
- The temporary high-energy state during a chemical reaction is known as the transition state.
Enzyme Structure and Function
- The region of the enzyme where the substrate binds and the catalytic reaction occurs is known as the active site.
- Molecules that increase the rate of a chemical reaction without being consumed in the process are known as catalysts.
Enzymatic Processes
- The process of breaking down a large molecule into smaller units using an enzyme is known as hydrolysis.
