Catabolic vs. Anabolic
• Talk to your neighbor.
• What is the difference.
• Which uses energy, which makes energy?

Energy forms
• Identify the picture as
either kinetic or
potential energy

• G
• Portion of energy able
to do work

work that cells can do?
• Chemical work
• Transport work
• Mechanical work

Amino acids
• 20 amino acids
• Joined together by peptide
bonds
• Amino acid polymer = peptide
• Structure determines function

proteins?

Structure
• What is the difference
between tertiary and
secondary structures?
explain how the catalytic cycle of an enzyme
that results in the production of a final product
Enzymes
• Use your book to define
the following
• Catalyst• Enzyme• Substrate• Active site
explain how the catalytic cycle of an enzyme
that results in the production of a final product
Enzymes
• Work by decreasing the
amount of energy
necessary for a
chemical reaction to
occur.
• If less energy is
necessary, what do you
predict will happen to
the speed of the
reaction?

Enzyme Properties
• They are proteins
• Make chemical reaction happen faster
• Are not used up in chemical reaction (reused
many times)
• Specific to only one kind of substrate
• Names usually end in ase
• Ex: lipase, Catalase, lactase
Proteins and enzymes are affected by
the following:
analyze and predict the effect of enzymes in
reactions
• Predict why pH and
temperature affect
enzymatic activity
analyze and predict the effect of enzymes in
reactions
• Competitive and noncompetitive inhibitor
