4.3 Study Guide Flashcards
When does fermentation occur?
during the lack of oxygen
What does fermentation use?
pyruvate from glycolysis
What does fermentation regenerate?
NAD+
What are the types of fermentation?
alcoholic and lactic acid
What stops in the absence of oxygen?
link/kreb cycle and E.T.C.
What does fermentation do?
allow for glycolysis to continue
What does alcoholic fermentation produce?
ethanol and CO2
What does lactic acid fermentation produce?
lactate/lactic acid
What cellular processes happen in the presence of O2?
glycolysis, prep step/kreb cycle, and E.T.C.
What cellular processes happen in the absence of O2?
glycolysis and fermentation
How much ATP is made in the presence of O2?
glycolysis - 2ATP
krebs cycle - 2ATP
E.T.C. - 25ATP
