Respiration Flashcards
what is respiration?
Respiration is the release of energy from food. It happens in every cell of every living thing. Viruses don’t respire.
what is the word equation for aerobic respiration?
sugar + oxygen —> carbon dioxide + water
what is the chemical equation for aerobic respiration?
C6H12O6 + 6O2 —> 6CO2 + 6H2O
what is aerobic respiration?
respiration that releases energy from sugar.
what is anerobic respiration?
respiration that releases energy from sugar without using oxygen
what is the word equation to anerobic respiration in yeast?
sugar —> ethanol + carbon dioxide
what is the chemical equation for respiration in yeast?
C6H12O6 —> 2C2H3OH + 2CO2
what is the word equation for anerobic respiration in muscle cells?
glucose —> lactic acid
what are the similarities between aerobic and anerobic respiration?
energy released by breakdown of sugar
ATP is made
some energy lost as heat
use glucose
what are the characteristics unique to aerobic respiration?
uses oxygen gas
no alcohol or lactic acid made
large amount of energy released
CO2 always made
what are the unique characteristics to anerobic respiration?
doesn’t use oxygen gas
alcohol or lactic gas made
small amount of energy released
CO2 sometimes made
where does respiration happen in the cell?
mitochondria
what us the energy released from the glucose used to make?
ATP
where does the cell get energy from?
ATP
which type of respiration makes more ATP?
aerobic respiration (living organisms)
