MICB 201 Chapter Notes - Chapter 17: Heterotroph, Nicotinamide Adenine Dinucleotide
Document Summary
Electrons come from an organic energy source before entering the etc. Respiration of energy sources containing n and s. Proteins that contain nitrogen and sulfur end up as waste products. Cytoplasmic enzymes remove the nitrogen and sulphur from the protein and end up in the environment. Only occurs when the protein is used as energy. Key point: waste products are dumped and end up in the environment. Degradation of energy sources and oxidation of c in energy sources. Not all organisms necessarily oxidize all the carbon in molecule to co2 (incomplete oxidation) Some organisms (through respiration) oxidizes ethanol (nutrient) acetic acid (waste) Note: no net change in oxidation of carbon (some are oxidized, some reduced) We are also fermenting right now, only way that rbc makes glucose. Gets more energy out of fermentation (yield is related to the net oxidation of carbon)
