Flashcards in B2 Biology - Aerobic and anaerobic respiration Deck (8)
what is aerobic respiration?
respiration using oxygen within animals and plants
what is the word equation for aerobic respiration?
glucose + oxygen --------- co2 + water + ENERGY
what are four examples of what the energy released by aerobic respiration is use for?
build up larger molecules from smaller ones
in animals to allow muscles to contract
mammals and birds - keep their body temp steady
in plants to build sugars and nutrients into amino acids then proteins
what does physical activity do to your breathing and heart rate?
increases breathing rate, makes you breathe more to demand for more oxygen
increases heart rate
what does your body require more of when doing exercise?
glucose and energy
what is anaerobic respiration?
incomplete breakdown of glucose which produces lactic acid
what does lactic acid do?
builds up in your muscles - painful
causes muscle fatigue
