What are the two types of anaerobic respiration? Where do they occur? How much ATP per molecule of glucose do they produce? What process do they both begin with?
Alcoholic fermentation and lactate fermentation. Cytoplasm. 2 ATP. Glycolysis.
1 of 7
Which organisms does lactate fermentation occur and what does it produce?
Mammals. Produces lactate.
2 of 7
Explain the processes of lactate fermentation.
Reduced NAD (from glycolysis) transfers hydrogen to pyruvate, forming lactate and NAD. NAD can be reused in glycolysis (production of lactate regenerates NAD)
3 of 7
How can some biological processes continue by lactate fermentation?
Because glycolysis uses NAD to take place so even without much oxygen, a small amount of ATP can be produced.
4 of 7
How does the body cope with too much lactate?
Liver takes up lactate in the blood stream and converts it back to glucose by gluconeogenesis.
5 of 7
Where does alcoholic fermentation take place and what does it produce?
Occurs in yeast cells and produces ethanol.
6 of 7
Explain the processes of alcoholic fermentation.
CO2 is removed from pyruvate to form ethanal. Reduced NAD from glycolysis transfers hydrogen to ethanal to form ethanol and NAD. NAD can then be reused in glycolysis. (production of ethanol also regenerates NAD to allow glycolysis to continue)
