AP Bio Unit 3 Review

Which of the following would NOT affect the function of an enzyme?

• Change in temperature

• Adding water

• Change in pH

• Change in salinity

 

An enzyme has a competitive inhibitor covalently bonded to its active site. What would be true about this enzyme?

• Increasing the substrate concentration will improve enzyme function

• Increasing enzyme concentration will increase enzyme function

• The enzyme is irreversibly inactivated by the covalent bonding of the inhibitor

• Changing the coenzyme will increase the activity of the enzyme

What is true of the reaction shown in the image?

• Adding more enzyme will increase the reaction rate

• Increasing the temperature will increase the reaction rate

• Adding more substrate will increase the reaction rate

• Increasing the pH will increase the reaction rate
