Molecular Biology Concepts Quiz week 12

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.
