1. BIOLOGY
PROTEINS

2. Protein Specialization
1. Contractile- movement
Actin and myosin in muscle tissue
Cilia and flagella undulations
2. Antibody- protection against disease
Produced by B-Cells in response to antigen
Transport- transport of other substances
Hemoglobin-protein in RBCs that transports oxygen through the body.
Transport proteins in cell membranes allow certain molecules in.

3. Proteins, cont. 4. Enzymes- catalyze metabolic processes
Lower activation energy
Increase speed of reaction
pH sensitive
Temperature sensitive
C A T E- contractile, antibody, transport, enzymes

4. Enzyme Action Enzymes are specific to a particular substrate
Enzymes have a binding site specific to a substrate
Enzymes bid the substratenew compound results
Can be:
Enzyme + 2 substrates = one compound
Enzyme + 1 substrate = two compounds

5. Protein Function Determined by folding pattern of protein.
Certain molecules on amino acids have affinity for other molecules
Results in bonding, which causes protein to fold a certain way.
Denaturing a protein is breaking up the folding pattern, which makes the protein ineffective
Ex. Frying an egg
