4.3 - aerobic and anaerobic respiration

what is cellular respiration?

exothermic reaction which transfers energy from glucose and continuously occurs in living cells

what are 3 uses of energy in organisms?

building larger molecules out of smaller ones, muscle contractions and maintaining body temperature

what is metabolism?

all the chemical processes that occur within a living organism to maintain life

where does aerobi respiration happen?

in the mitochondria

what is the word equation for aerobic respiration?

glucose + oxygen → carbon dioxide + water

what is the symbol equation for aerobic respiration?

C6H1206 +6O2 → 6CO2 + H20

what is the word equation for anaerobic respiration?

glucose → lactic acid

what is the word equation for anaerobic respiration in plants and yeast?

glucose → ethanol + carbon dioxide

what is anerobic respiration in yeast called?

fermentation which is used in industry to make bread and alcohol

what 2 reasons make animal cells prefer aerobic respiration?

anaerobic respiration doesn’t break down the glucose completely and so releases less energy. anaerobic respiration produces lactic acid which can damage cells and lead to oxygen debt
