Example Question #2 : Cell Biology
Which of the following characteristics are true of all enzymes?
Enzymes are sensitive to temperature and pH.
None of the answer choices are correct.
Enzymes do not alter the equilibrium constant.
Enzymes are not used up in the reaction.
Three of the answer choices are correct.
Three of the answer choices are correct.
Enzymes do not alter the equilibrium constant because enzymes are not consumed in the reaction.
Hint: Write out the equation for the equilibrium constant and notice that there is no variable for enzymes.
Enzymes are sensitive to temperature and pH, as high temperatures and very low pH can cause denaturation of an enzyme. Enzymes are only optimal at certain pH and temperature ranges.
