Which of the following is true about enzymes? Enzymes operate under a wide range of temperatures and pH. Enzymes catalyze reactions in only one direction. Enzymes reaction rates are generally slower than other chemical catalysts. Enzymes show very little specificity for their substrates. Enzyme activities can often be regulated.

Which of the following are correct regarding enzymes? Select all that apply. Enzymes require stable environmental conditions. Enzymes can work across a wide range of environmental conditions. Changes in pH or temperature do not cause changes in protein shape. Changes in pH or temperature can cause changes in protein shape. Enzyme shape change changes enzyme function. Enzymes are catalysts. Enzymes can make reactions happen that would never occur without them. Enzymes speed up reactions but cannot make reactions happen that would not normally occur.

Which of the following statements regarding enzymes is false? Enzymes are generally sensitive to fluctuations in pH and temperature of the reaction environment. Enzyme function depends on the three-dimensional structure or conformation of the enzyme. Enzymes only catalyze reactions involving one substrate. Enzymes are generally composed of proteins. Enzyme activity can be lowered if their active site is bound with a competitive inhibitor.
