respiration and exercise Flashcards
true or false
respiration is breathing in and out
false
its not at all
what is respiration ?
- its the process of releasing energy from glucose which goes to every cell
where and whats dose respiration take place ?
- happens every cell everywhere
- all living thing ,plant , human etc
- happens in the mitrchdria
what is aerobic respiration ?
- is respiration using oxygen .
- most efficient way to release energy from glucose
what is the word equation for aerobic respiration ?
glucose + oxygen —–> carbon dioxide + water + energy+
what can energy used form aerobic respiration be used for ?
- to build up larger molecules from smaller one like proteins from amino acids
- in mammals and birds to keep the dot temperature steady
- in animals to allow muscle contraction
- in plants to build up sugars , nitrates and other nutrients into amino acids which are then built up into protein
why does physical activity increase …….
- breathing rate makes you breathe more deeply to meet the demand for extra oxygen
- speed at which the heart pumps blood
true or false ?
glycogen is not used during exercise
this false its used
where is glycogen stored ?
- ## mainly scored in the liver but each muscle has its own store
during lots of exercise muscles use glucose….
- rapidly , so some of the stored glycogen is connected bak to glucose to provide ,more energy
when does anaerobic respiration start ?
- when lots of excise starts to happen and your body can’t supply enough oxygen to your muscles they start ana respiration
what does anaerobic mean ?
- without oxygen
- its the incomplete breakdown of glucose which produces lattice acid
formula for anaerobic respiration
- glucose —> energy + lactic acid
what area the down sides anaerobic respiration
- lot less energy is given out because only partially breaks down glucose
- lactic acid which is produced , painful and creates oxygen debt
what is muscle fatigue
- muscles get tired and contract less , efficiently less
