2.8 respiration

def: cell respiration

the controlled release of energy from organic compounds in cell to produce ATP

why is respiration important

provides cell with energy
required for life processes

products of glyocosis

small amount of ATP, pyruvate

products of aerobic cell respiration

water, CO2, large amount of ATP

products of anerobic cell respiration (in humans)

lactate

products of anerobic cell respiration in yeast

ethanol and CO2

where does gycolosis occur

cytoplasm

where does aerobic cell respiration occur?

mitochondria

where does anerobic cell respiration occur?

cytoplasm

summarize glycolysis

glucose broken down into pyruvate, a small amount of ATP is produced

summarize aerobic cell respiration

pyruvate is further broken down using oxygen into CO2 and H2O -> large amount of ATP is produced

summarize anerobic cell respiration

pyruvate is further broken wo oxygen into lactate in humans, into ethanol and CO2 in yeast, with no additional ATP is produced

outline similarities between aerobic and anerobic cell respiration

both start w glucose, glycolysis both produce/use pyruvate both produce some ATP, CO2

outline the differences between aerobic and anaerobic cell respiration

* aerobic uses oxygen, anerobic does not aerobic occurs in mitochondria, anerobic occurs in cytoplasm
* anerobic produces lactate in humans, ethanol and CO2 in yeast, anaerobic produces CO2 and water
* aerobic produces a large amount of ATP, anerobic produces a small amount of ATP
