2.  Enzymes are proteins that speed up chemical reactions in the body.

3.  Each enzyme has only one specific reaction it can perform.

4.  Yes, the same enzyme molecule can be used over and over

5.  The shape of an enzyme determines its function.

6.  Denaturing is when extreme pH or high temperature change the shape of the enzyme making it less or ineffective.

8.  An enzyme align 2 molecules, enabling them to bond and form a larger molecule.

10.  Enzymes can only bond with molecules that physically fit

12.  A single enzyme reacts with several of the same molecule, creating a chain of that molecule

14.  An enzyme can be denatured by temperature or pH extreme.  The shape of the enzyme is changed and becomes inactive.

15.  The process of denaturing is NOT reversible.  Once an enzyme is denatured it will never be effective again

16.  The enzyme actually changes its shape and will not fit with the substrate it was meant for.

18.  The substrate is the “thing” the enzyme is acting upon.  The product is what is produced from the enzyme and substrate reaction. Area that the substrate and enzyme meet is know as the active site.

19.  Coenzymes help make a fit between the enzyme and coenzyme when necessary.  Coenzymes are made of vitamins and minerals

20.  An inhibitor blocks/prevents a reaction from happening.

21.  They prevent reactions from happening that are vital to life.

23.  The higher the concentration of the substrate the slower the reaction.  The lower the concentration of the substrate the faster the reaction.

24.  The higher the concentration of an enzyme, the faster the reaction.  The lower the concentration of an enzyme, the slower the reaction.

25.  The enzyme prefix is usually after the substrate it acts upon.  The suffix or ending is usually “ase”  Example:  Lipase is an enzyme because it ends in “ase”  We know it acts upon lipids because it starts in “lip”
