Oxygen Requirements and Other requirments
- Anerobes
- Obligate anaerobes: oxygen is essential or deadly?
- Obligate anaerobes: oxygen is essential or deadly?
- Obligate aerobes: it is essential because it seves as the final electron acceptor of the electron transport?
- Atmospheric oxygen nor covaletnly bound oxygen such as in carbohydrates and water is poisonous: the TOXIC forms of oxygen is those that are deadly.
- these toxins forms like to steal electrons from other compounds-- this results in: results in vigorous oxidations: causes irreparable damage because they are oxidizing important compunds
- Singlet oxygen: its a molecular oxygen with electrons that have been boosted to a higher? ____state. (they drank red bull)->known in aerobic metab.
- Phagocytic cells (white human blood cells) use this to oxidize pathogens
- How is this deadly?
- Phagocytic cells (white human blood cells) use this to oxidize pathogens
- Singlet oxygen: its a molecular oxygen with electrons that have been boosted to a higher? ____state. (they drank red bull)->known in aerobic metab.
- Superoxide radical: can be so reactive and toxic that aerobic organisms must produce enzymes call superoxide dismatases to detoxify them
- Peroxide anion: hydrogen peroxide is formed during reactions catalyzed by superoxide dismutase contains this
- this makes hydrogen peroxide which is an antimicorbial agent
- this makes hydrogen peroxide which is an antimicorbial agent
- these toxins forms like to steal electrons from other compounds-- this results in: results in vigorous oxidations: causes irreparable damage because they are oxidizing important compunds
- Atmospheric oxygen nor covaletnly bound oxygen such as in carbohydrates and water is poisonous: the TOXIC forms of oxygen is those that are deadly.
- Aerobes
- contains either catalase or peroxidase , these detoxify peroxide anion
- contains either catalase or peroxidase , these detoxify peroxide anion
- Other chemical requirments
- Trace elements
- Required in very small amounts
- example: very small amounts of _______ (starts with S)-- is dissolved out of the walls of glass test tubes-- thus providing the total requirement for algae to grow.
- Just as an FYI: growth factors are necessary organic chemicals -- vitamins are growth factors for some microorganisms-- vitamis can constitute all or part of coenzymes. --
- Vitamins are not growth factors for microorganisms that can manufacture vitamins-- such as E. Coli
- Growth factors for various microbes will include some amino acids, purines, pyrimidines, cholesterol, NADH, and heme. :)
