ENZYMES 1. Importance A. Determines biochemical activity (metabolic reactions). B. Inherited characteristic so biochemical activity used for identification classification, classification. C. Chemical agents, antibiotics often interfere with enzyme activity to inhibit bacterial growth. D. Responsible for many pathological changes in host tissue. E. Industrial application dependent on enzyme activity of bacterial cell. F. Environmental activity dependent on enzymes produced by bacterial cell. 2. Characteristics A. Large globular proteins. B. Heat sensitive - 10 ° doubles activity; easily denatured by excess heat C. pH sensitive - easily denatured by acid, alkaline conditions. D. Organic catalysts - speed up reactions by lowering activation energy. E. Specific in action - reacts with one particular substrate , catalyze one type reaction. F. Specificity is determined by active site on enzyme. that is complementary to combining site on substrate.

Unformatted text preview: G. Do not directly enter reaction, remain unchanged, so can react with another molecule of same substrate. 3. Coenzymes, Cofactors A. Coenzymes 1. Organic molecules - vitamins 2. "Carrier" molecules - transfer electrons from one molecule to another. B. Cofactors 1. Inorganic molecules - metal ions 2. Completes structure of active site on enzyme so that it is complementary to combining site on substrate. 4. Grouping, Naming Enzymes A. Grouped - type chemical reaction they catalyze B. Named - type chemical reaction catalyzed, specific substrate on which they act. C. Names - end in "ase." 5. Two Groups Bacterial Enzymes A. Exoenzymes - excreted; break down large complex compounds into smaller ones that can cross the cell membrane. B. Endoenzymes - remain inside cell; involved in the production of energy and cell parts. 1 2...
