Energy Fermentation week 13 (DONE)

Which type of fermentation enables glycolysis to continue ATP synthesis under anaerobic conditions in baker’s yeast (single-cell Fungus) cells?

alcoholic fermentation (ethanol fermentation)

Which type of fermentation enables glycolysis to continue ATP synthesis under anaerobic conditions in human cells?

Lactic acid fermentation

When oxygen is depleted in your muscle cells due to exercise, what process enables your muscle cells to temporarily make ATP by glycolysis?

Lactic acid fermenation allows muscle cells to continue ATP production via glycolysis

Which Fermentation product enable glycolysis to continue producing ATP under anaerobic conditions?

lactate or ethanol

Which glycolytic enzyme requires NAD+ as a substrate?

glyceraldehyde 3-phosphate dehydrogenase (G3P dehydrogenase)

What are the products of lactic acid fermentation in human cell?

Lactate (lactic acid), NAD+ and ATP

Which enzyme performs lactic acid fermentation in your cells?

Lactate dehydrogenase (LDH)

How does you body reuse the lactate molecule produced by LDH?

lactate converts back to pyruvate, then glucose and returned to muscles for energy

Can lactic acid fermentation satisfy the long term energy needs of your cells?

No, lactic acid fermentation provides rapid and small amounts of ATP suitable for short-term needs

How many minutes can your muscle cells perform lactic acid fermentation?

1 to 3 minutes

Does alcohol (ethanol) fermentation in baker’s yeast produce ethanol & CO2?

Yes, both are fermentation products in yeast

How are CO2 molecules relevant to baking & brewing?

creates bubbles that give structure and texture

Which product of alcohol fermentation destroy harmful microbes in that water used to make beer & wine?

ethanol (alcohol)

Which fermented foods did our ancestors make using alcohol fermentation?

Beer, wine, cider, and mead
