anaerobic respiration Flashcards
what is anaerobic respiration
doesnt require oxygen
what stages does anaerobic not use
link reaction, krebs cycle and oxidative phosphorylation
what are the two types of anaerobic respiration
alcoholic fermentation
lactate fermentation
what does anaerobic respiration start with
glycolysis in the cytoplasm
which organisms use lactate fermentation
mammals
what is the product of lactate fermentation
lactate
what is the first stage of lactate fermentation
NADH from glycolysis transfers hydrogen to pyruvate to form lactate and NAD
what is the NAD produced from lactate fermentation used for
reused in glycolysis to produce small amounts of ATP
when can our cells tolerate high levels of lactate
short periods of intense exercise when ATP supply is not efficient
when is lactate toxic
when too much of it is present in the blood
how does our body remove lactate
the liver takes it up from the bloodstream and converts it back into glucose via gluconeogenesis
which organisms use alcoholic fermentation
yeast cells
what does alcoholic fermentation produce
ethanol
what is the first stage of alcoholic fermentation
CO2 is removed from pyruvate to form ethanal
how is ethanol formed from ethanal in alcoholic fermentation
NADH from glycolysis transfers a hydrogen to form ethanol and NAD
