respiration Flashcards
define respiration
the process of transferring energy from glucose, which happens constantly in every living cell
chemical equation of aerobic respiration
C6H12O6 + 6O2 → 6CO2 + 6H2O +energy
what is the difference between aerobic and anaeroebic respiration
-aerobic respiration occurs when there is plenty of oxygen available
-anaerobic respiration occurs when there is no oxygen
where does aerobic respiration take place
mitochondria and cytoplasm
where does anaerobic respiration take place
cytoplasm
word equation of anaerobic respiration
glucose -> lactic acid +energy
word equation of anaerobic respiration in plants/yeast
glucose -> ethanol + carbon dioxide + energy
difference in the amount of energy released in aerobic and anaerobic respiration
-aerobic releases large amount of energy
-anaerobic respiration releases small amount of glucose
how is the glucose broken down in anaerobic respiration
partially broken down
what does lactic acid build up lead to
-painful and leads to cramps
what happens when you exercise(anaerobic)
-body can’t supply enough oxygen to your muscles for aerobic respiration
-heart rate and breathing rate increases as much as they can
-muscles start respirating anaerobically as well
why is breathing rate higher when exercising
-greater demand for oxygen, increased breathing rate allows for more oxygen to be absorbed into the blood
-aerobic respiration, muscles require energy to contract
-CO2 needs to e removed
-lactic acid needs to be oxidised and removed
Why does anaerobic respiration lead to less energy
Lactic acid is produced, which has a low pH, affecting the enzymes in cells, so less energy is produced
