2 pyruvates are created from 2 PGAL's (3C) Producing 4 ATP's and 2 NADH's Net production = 2ATP’s and 3 NADH’s
WHERE DOES IT OCCUR? No oxygen is used 2 Acetaldehyde is reduced by NADH to ethanol Regenerating supply of NAD+ Carbon dioxide may be realeased Glycolysis continues IN THE CYTOSOL OF YEAST!
When the first step occurs and 2 acetaldehyde is formed, 2 CO ₂ is released Then acetaldehyde accepts hydrogen and electrons from the 2 NADH formed through Glycolysis With the combining of e-, H+, and 2 acetaldehyde, 2 NAD+ is regenerated and 2ethanol is created
ALCOHOLIC FERMENTATION: Glucose + 2 ADP + 2 Pі 2 ethanol + 2 CO ₂ + 2 ATP + 2 H ₂ O OR C ₆ H ₁₂ O ₆ 2 C ₂ H ₅ OH + 2 CO 2 LACTIC ACID FERMENTATION: Glucose + 2 ADP + 2 Pi 2 lactate + ATP + 2 H ₂ O
Fermented vegetables Pickles! The sugars in the pickles are converted to lactic acid, preserving the pickle Lactobacillus bulgaricus – a bacteria Yogurt Lactose is fermented by the bacteria to lactic acid, which both thickens the yogurt and restricts the growth of bacteria that poisons the food Humans during anaerobic exercise lactic acid is fermented in muscles where oxygen is depleted makes muscles burn
