Document Summary

Which is false: glucose (larger molecule) to co2 (smaller molecule) is oxidation, losing electrons and lots more. Associated with heterotrophic catabolism: methane - organic, produced naturally by archaea, oxidation - organic (heterotrophic metabolism) Shortly after primary producers bloom, secondary producers consume the primary creating co2. Bioremediation: the use of life forms (usually microbial) to degrade pollutants. Or reduction, in fermentation or as terminal electron acceptors (anaerobic respiration) *its all about the flow of electrons - following the philosophy of garage sales (one mans trash is another mans treasure) if one organism produces co2 another is going to consume co2, etc. Most often exploiting the phenomenon that collectively, heterotrophic microbes degrade (oxidize) everything, (ex: dtd, microbes will find the ability to use it) Figure 16. 32 sewage treatment facilities and water purification plants. Currently only a few good success stories in bioremediation. Methanogens: obligately anaerobic archaea ch4 is an end-product of anaerobic (heterotrophic) catabolism.
