enzymes review

What happens during enzyme denaturation?

• The enzyme becomes more specific and can bind to more substrates
• The shape of the enzyme remains the same and it can still bind to substrates
• The shape of the enzyme changes and it can no longer bind to substrates
• The enzyme becomes more efficient and can break bonds faster

Which of the following factors can affect enzyme function?

• Light intensity and humidity
• pH, temperature, and concentration levels
• Atmospheric pressure and wind speed
• Gravity and magnetic fields

What is the optimal pH for most enzymes?

• It varies depending on the environment
• 8-14
• 7
• 1-6

What is the process of breaking bonds in a chemical reaction called?

• Dehydration synthesis
• Hydrolysis
• Denaturation
• Catalysis

What is the effect of increasing enzyme concentration while keeping substrate concentration constant?

• Reaction rate becomes more specific
• Reaction rate remains constant
• Reaction rate increases
• Reaction rate decreases

What is the effect of increasing enzyme concentration on reaction rate?

• Reaction rate becomes more specific
• Reaction rate decreases
• Reaction rate remains constant
• Reaction rate increases

What is the effect of decreasing enzyme concentration on reaction rate?

• Reaction rate increases
• Reaction rate becomes more specific
• Reaction rate decreases
• Reaction rate remains constant

What is the relationship between enzyme shape and substrate specificity?

• Enzymes with different shapes can bind to the same substrate
• Enzymes with specific shapes can only bind to specific substrates
• Enzymes with no shape cannot bind to any substrates
• Enzymes with the same shape can bind to different substrates

Why are enzymes important in biological processes?

• They can break bonds and release energy
• They can deactivate inhibitors
• They can change shape to bind to different substrates
• They can be used over and over again for the same reaction

What is the optimal temperature range for enzyme function?

• 32-40ºF
• 68-86ºF
• 95-104ºF
• 140-158ºF
