Metabolic pathway in absence of oxygen
Metabolic pathway in absence of oxygen
Anaerobic fermentation
Why ETC stops without oxygen
Why ETC stops without oxygen
No oxygen to accept electrons and protons
ATP produced by glycolysis per glucose
ATP produced by glycolysis per glucose
2 ATP
Products of lactic acid fermentation
Products of lactic acid fermentation
2 lactic acid + 2 ATP
Products of ethanol fermentation in yeasts
Products of ethanol fermentation in yeasts
2 ethanol + 2 CO₂ + 2 ATP
Location of anaerobic fermentation
Location of anaerobic fermentation
Cytosol
Why fermentation regenerates NAD⁺
Why fermentation regenerates NAD⁺
To keep glycolysis running
ATP per glucose: aerobic vs anaerobic
ATP per glucose: aerobic vs anaerobic
30-32 ATP vs 2 ATP
Why lactic acid is toxic
Why lactic acid is toxic
Lowers pH, can denature enzymes
CO₂ role in bread making from yeast fermentation
CO₂ role in bread making from yeast fermentation
Makes bread rise/expand
