What does a reaction with ΔG>0 indicate?

• The reaction is exothermic.

• The reaction is endothermic.

• The reaction is spontaneous.

• The reaction releases energy.

What is the role of enzymes in chemical reactions?

• They increase the temperature of the reaction.

• They decrease the activation energy required.

• They change the products of the reaction.

• They increase the pH of the reaction.

What is competitive regulation in enzymatic activity?

• Inhibitor binds to a site other than the active site.

• Inhibitor competes with the substrate for the active site.

• Enzyme is permanently deactivated.

• Enzyme activity is increased by the inhibitor.

What is metabolism?

• The breakdown of molecules only.

• The synthesis of molecules only.

• The sum of all chemical reactions in a cell.
