Bio Lab- Fermentation

what is fermentation?

metabolic process, releases energy from a sugar9or other organic molecule), produces 2 ATP, good process for small anaerobic organisms like deep swamp bacteria or innermost intestinal bacteria

what is the formula for fermentation?

glucose--> 2CO2 + 2ethanol + 2 ATP

what is cell respiration?

metabolic proces, releases energy from sugar (or other organic molecule), produces 36-38 ATP, good process for larger organisms like humans (aerobes)

what is the formula for cell respiration?

glucose + 6 O2---> 6CO2 + 6 H2O + 36-38 ATP

what is the definition of aerobes?

organisms requiring O2 for their metabolism- need oxygen

what is the definition of anaerobes?

organisms not requiring O2 for their metabolism - doesn't need oxygen

what is facultative anaerobes?

organisms that can be metabolize in conditions with or without O2; therefore they do cellular respiration and do fermentation. ex: single-celled fungi called yeast

what are products of yeast fermentation?

malt--> beer (ethanol +foam)

grape juice--> wine (ethanol)

flour and sugar--> bread (CO2-rise)

agricultural waste--> fuel (ethanol)

what are products of bacterial fermentation?

swiss cheese, sour cream, yogurt, sauerkraut, soy sauce, pickles
