Amino acids

• 20 amino acids• Joined together by peptide

bonds• Amino acid polymer = peptide

• Structure determines function• What element is added in

proteins?

• Primary Structure• Secondary Structure• Tertiary Structure• Quaternary

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?

enzymeActive sitereactant

substrate catalase

Activation Energy

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 non-competitive inhibitor
