2. Watch the animation and read the labels.
3. Take notes in your online notebook over the video and the labels.
Lactate fermentation: Pyruvate accepts electrons and hydrogen from NADH. This creates 2 NAD+ and changes pyruvate to lactate. Glycolysis causes 2 ATP to be created during this reaction.
Alcoholic fermentation: The release of carbon dioxide causes pyruvate to convert into acetaldehyde. Acetaldehyde accepts electron and hydrogen. This regenerates NAD+ and creates ethanol. Glycolysis causes 2 ATP to be created during this reaction.
4. Record any need-to-knows you still have in this journal response.
