Respiration Flashcards
when does aerobic respiration take place
it occurs all the time
when does anaerobic respiration take place
when there is a lack of oxygen
where does aerobic respiration take place
Mitochondria
where does anaerobic respiration take place
in the muscles
what is the word equation for aerobic respiration
oxygen + glucose - Carbon dioxide + water + Energy
what is the order once trachea is split
Trachea, Bronchi, Bronchioles, Alveoli
“the particles move to the capillaries” what is this process called
diffusion
what is diffusion
The movement of particles from a low concentration to a high concentration
what is glycogen
a store of glucose in the liver
what happens to the blood vessels - Vasodilation
the widening of blood vessels
what happens to the blood vessels - Vasoconstriction
the narrowing of blood vessels
what is metabolism
the sum of all the reactions in the body
name the three words that must be used in an exam.
oxidise, release, diffusion
what is the equation of anaerobic respiration
glucose —- lactic acid
what is the equation for anaerobic respiration in plants and yeast
glucose —- ethanol + carbon dioxide
why is respiration important
respiration is the process of transferring energy from glucose which goes on in every cell.
you need energy to keep your body going
what happens to the body during anaerobic respiration exercise
when you do vigorous exercise your body cannot supply enough oxygen to your muscles
therefore the muscles start to anaerobic respirate as well as aerobic respiration
anaerobic respiration is the incomplete breakdown of glucose making lactic acid and a small amount of energy
it does not transfer nearly as much energy as aerobic respiration
during exercise it allows your to keep on using your muscles for a while longer
how is anaerobic respiration by yeast useful
because it can be used in fermentation,
in the food and drink industry can be used in beer and Bread
in bread making its the carbon dioxide from fermentation which makes the bread rise
in beer and wine making its the fermentation process that produces alcohol
what is muscle fatigue
when the muscles get tired and then stop contracting efficiently
what is oxygen dept
the amount of extra oxygen your body needs to react with the build up of lactic acid and remove it from the cells.
oxygen reacts with lactic acid to form harmless CO2 and water
how is the liver involved in repaying the oxygen dept
the second way of coping with high levels of lactic acid is,
the blood that enters your muscles transports the lactic acid to the liver
in the liver the lactic acid is converted back to glucose
