6B- anaerobic fermentation Flashcards
(7 cards)
anerobic fermentation
- breakdown of glucose and ATP production via glycolysis in the absence of oxygen.
-It allows for the replenishment of NAD+ for continued use in glycolysis.
process of anerobic fermentation
-through glycolysis although it does not produce much ATP.
- cell must still find a way to convert NADH back to NAD+, which is an input of glycolysis, without use of oxygen.
- Thus extra reactions of anaerobic fermentation take place.
anerobic fermentation in animals and yeast
have developed two different mechanisms to cycle NADH and regenerate NAD+. These involve fermentation of pyruvate, the end product of glycolysis
anerobic fermentation in animals
-conversion of pyruvate to lactic acid in animals
-when oxygen is absent or lack of, lactic acid fermentation after glycolysis.
-process breaks down pyruvate into lactic acid and cycles NADH back to NAD+ for reuse in glycolysis
Lactic acid fermentation
Lactic acid fermentation is the process by which a human cell produces ATP in the absence of oxygen. In this process, glucose is broken down to produce ATP and lactic acid as a by-product.
-In human cells, anaerobic respiration takes the form of lactic acid fermentation.
-products in human cells are: ATP (small amount) and Lactic acid (product of glucose breakdown
anerobic fermentation in animals
conversion of pyruvate to ethanol and carbon dioxide in yeast.
