Microbiology Test #2
| Question | Answer |
|---|---|
| Metabolism | the sum of all chemical reactions which take place in a cell |
| Anabolism | build up of larger compound from smaller ones: energy used |
| Catabolism | break down of large compound to smaller: energy produced |
| Enzyme | biological catalysts that are involved in chemical reactions they are proteins they are very sensitive to adverse conditions 30 degrees Celsius, neutral pH they are involved in 300-400 reactions/sec |
| Exoenzyme | enzymes are produced within the microbial cell but the action takes place Outside the cell |
| Starch ----> Simple Sugars | Amylase 80% starch, broken down in mouth by salivary glands 20% by pancreatic amylase in pancreas |
| Lipids(Fats)---> Fatty Acids & Glycerol | Lipase |
| Protein ---> Amino Acids | Protease |
| Endoenzyme | they are all produced within a microbial cell and action takes place inside of cell ex. all enzymes in metabolic pathways |
| Carbohydrates | starch--> glucose (amylase) Glycolosis: 1 glucose -> Pyruvic Acid Krebs Cycle: Pyruvic Acid -> CO2+ H20 + 2 ATP Electron Transfer: Produces 34 ATP Total 38 ATPs from 1 Glucose |
