Enzymes are able to speed up chemical reactions because they - 

• increase the temperature inside the cell
• reduce the friction between the reactants
• make the raw materials more chemically reactive
• lower the activation energy of the reaction

Which of the following statements suggests that the shape of an enzyme determines the enzyme’s function?
 

• Enzymes active sites are specific to a substrate.
• Enzymes can operate in a wide range of conditions.
• Enzymes are activated by neighboring molecules.
•  Enzymes can be found in all life-forms. 

Which of these is most likely an enzyme?  (Based on the suffix)

• Sucrose
• Saccharide
• Fructose
• Amylase
