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