BIOL 2051 Study Guide - Midterm Guide: Ethanol Fermentation, Citric Acid Cycle, Anaerobic Respiration
Document Summary
At this point, pyruvate can either be used: In fermentation to form fermentation products (alcohols, acids, gases) or. In respiration (tca cycle) to be fully oxidized to co2. From 1 glucose molecule a net of 2 atp are produced. Reduction of pyruvate fermentation products: nad, respiration. From 1 glucose molecule up to 38 atp are produced (under ideal conditions) Uses electron transport chain (etc) and atp synthase. Types of fermentation: homolactic fermentation- once electrons from nadh are passed to pyruvate, pyruvate is reduced to lactic acid, ex. Lactobacillus ferments lactose sugar in milk to produce lactic acid, this gives us yogurt: alcoholic fermentation- once electrons are passed from nadh to pyruvate, pyruvate is reduced to alcohol and co2, ex. Final electron acceptor may be an inorganic compound such as nitrate, ferric iron, sulfate, or carbonate: in fermentation, the final electron acceptor is made by the cell from the electron donor.
