What does activation energy refer to?

• The amount of energy at the beginning of a reaction.

• A thermodynamic barrier that must be overcome for a reaction to occur.

• The amount of energy released during the complete breakdown of a reactant.

• The amount of energy at the end of a reaction.

Enzyme X has an optimum rate of reaction at 97 degrees Fahrenheit. How would rate of reaction be affected if temperature fell to 92 degrees Fahrenheit?

• increase - not as hot

• decrease - no substrate would be produced

• increase - more substrate would be produced

• decrease - cause a change in the shape of the protein
