BACTERIAL METABOLISM METABOLISM 1. Definition: all chemical processes occurring in living cells. A. Catabolism - chemical reactions involved in breakdown of complex compounds into simple ones; release energy . B. Anabolism - chemical reactions involved in synthesis of complex compounds from simple ones; utilize energy . 2. Some general principles of metabolism - the chemical reactions involved in metabolism: A. Consist of many overlapping reactions occurring in orderly stepwise fashion, called pathways . B. Many intermediate products are produced between starting reaction and end products. C. All reactions require 1). ENERGY 2). CATALYST 3. Metabolic Pathways A. Photosynthesis 1. Occurs in cells that produce chlorophyll 2. Catalyst:

Phototrophs : a. Photoautotrophs - utilize inorganic compounds (i.e., CO 2 ) b. Photoheterotrophs - utilize organic compounds (i.e., methanol) B. Chemosynthesis 1. Occurs in cells that do not produce chlorophyll. 2. Energy: produced by oxidation of chemical compounds (i.e., sugars). 3. Catalyst: enzymes produced by cell. 4. Chemotrophs : a. Chemoautotrophs - utilize inorganic compounds (i.e., CO 2 ) b. Chemoheterotrophs - utilize organic compounds (i.e., glucose) 1 2...
