By reducing activation energy
By reducing energy produced by the reaction
By increasing activation energy
By increasing energy produced by the reaction
Antacids break the covalent bonds within pepsin.
Pepsin dissolves antacids in the gastric juice.
The active site of pepsin changes shape.
The concentration of pepsin increases.
Student 1; enzymes are depleted as a reaction progresses.
Student 1; enzymes are not depleted as a reaction progresses.
Student 2; enzymes are depleted as a reaction progresses.
Student 2; enzymes are not depleted as a reaction progresses.
Happen too fast.
Occur at much the same rate as they do with enzymes.
Require a different pH.
Occur too slowly to support life processes.
Enzymes work best at a specified pH.
All enzymes have the same shape as their substrates.
Enzymes are proteins.
The shape of an enzyme allows it to do its job.
Catalysts slow down the rate of chemical reactions.
All catalysts are enzymes.
Catalysts are used up during a chemical reaction.
Catalysts lower the activation energy of a chemical reaction.
Products of the reaction.
Speed of the reaction.
Temperature of the reaction.
PH of the reaction.
Where the reactant fits into the enzyme
Where the enzymes and molecule bond together
When the balance of living organisms affects the enzyme
The same shape in all enzymes
Probably occurred in the presence of a catalyst.
Requires a greater activation energy than reaction 2.
Is the same as reaction 1, but faster.
Takes longer than reaction 2.
