Enzyme/ATP Review

Which of these best describes an exothermic reaction?

• it does not absorb or release any energy

• the products have higher energy than the reactants

• the products and reactants have an equal amount of energy

• it releases more energy than it absorbs

Identify the products in this reaction: 6H2O + 6CO2 --> C6H12O6 + 6O2

• 6H2O and 6CO2

• C6H12O6 and 6O2

• 6CO2 and 6O2

• 6H20, 6CO2, C6H12O6, and 6O2

A chemical reaction that absorbs energy is called

• endothermic

• exothermic

• catalyzed

• enzyme

When activation energy is lowered, what happens to the rate of the chemical reaction?

• the reaction is slower

• the rate of reaction doesn't change

• the reaction happens faster

• none of these

The molecule that binds to an enzyme is called

• monomer

• active site

• catalyst

• substrate

Substrates bind to the enzyme at a specific location. This location is called the

• catalyst

• active site

• substrate

• activation energy
