Protein Structure
Primary - sequence of amino acids
Secondary – folding into pleated
sheets or alpha helix
Tertiary – 3-D structure, completely
Most proteins stop here
Quaternary – interaction of several
protein molecules
2-4 Chemical Reactions and Enzymes
 biological
Speed up reactions
 Without them
reactions would
occur too slow for
 Lower the activation
Enzymes provide a site where substrates can
be brought together = Active Site (tertiary)
 The fit is like a lock and key
Enzyme Regulation
Work best at a
particular pH
Affected by changes
in temperature
Digestion enzyme
