respiration // exercise

HideShow resource information
respiration is...
the process of releasing energy from glucose
1 of 9
aerobic respiration..
respiration using oxygen
2 of 9
word equation for aerobic respiration is..
glucose + oxygen ---> carbon dioxide + water (+energy released)
3 of 9
four examples of what the energy released by aerobic respiration is used for:
to build up larger molecules from smaller ones. for animals; to allow the muscles to contract. in mammals it is used to keep the body temperature steady. in plants; to build up sugars, nitrates into amino acids which are then built up into proteins.

muscles use..
aerobic respiration which is used to contract them
5 of 9
physical activity:
increases your breathing rate and makes you breath deeper to keep up with the demand for oxygen. increases the speed at which your heart pumps.
6 of 9
anaerobic respiration ..
is when there is not enough oxygen produced during exercise. it produces lactic acid in your muscles which causes them to get tired and stop contracting.
7 of 9
word equation for anaerobic respiration
glucose --> energy + lactic acid
8 of 9
after anaerobic respiration..
when you stop exercising you'll have an oxygen debt. this means you have to keep breathing hard after you stop to get more oxygen into your blood. the blood flows through your muscles to remove the lactic acid by oxidising it,
