AQA BIOLOGY FOUNDATION-Respiration

what is aerobic respiration?

what is aerobic respiration?

a form of respiration that uses oxygen to release energy from molecules like glucose

what is anaerobic respiration?

a form of respiration that releases energy from molecules without using oxygen

what is cellular respiration?

an exothermic reaction which is continuously occurring in living cells

what is metabolism?

the sum of all the reactions in a cell or a body

what is fermentation?

anaerobic respiration in plants and yeast which produces ethanol and carbon dioxide

what is the aerobic respiration word equation?

glucose + oxygen———carbon dioxide + water

what is the anaerobic respiration word equation?

glucose————lactic acid

what is the aerobic respiration number equation in animals?

C6H12O6 + 6O2———6CO2 + 6H2O

what is the anaerobic respiration number equation in animals?

C6H12O6———2C3H6O3

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

glucose—— ethanol + carbon dioxide

what is the anaerobic respiration number equation in plants and yeast?

C6H12O6——2C2H5OH + 2CO2

what is oxygen debt?

the amount of extra oxygen the body needs after exercise to react with the lactic acid and remove it from cells

how does exercise effect our breathing?

as we exercise, our breathing rate increases to take in more oxygen and get rid of more carbon dioxide. when we stop exercising, there is a recovery time where we continue to have an increased breathing rate as we remove any lactic acid made. the fitter you are, the shorter that period is.
