Cell respiration
chemical reactions that happen in all living cells. it is the way that energy is released from glucose so that all other chemical processes can take place.
cellular respiration is the aerobic process by which living cells break down glucose molecules, release energy and form ATP molecules. overall this process involves glucose and oxygen reacting to form CO2 + H20.
aerobic and anaerobic
aerobic respiration is when the body is respiring using O2, while breaking down glycogen.
anaerobic respiration is when the body is working overtime and there is too much energy needed so without O2, lactic acid is produced.
after a short amount of time the lactic acid build up will begin to cause pain in muscles, which can then become poisonous.

yeast: yeast causes gas causing the bread to rise. kneading the bread makes the yeast respire. O2 is used up very quickly therefore it is an anaerobic process.
bioethanol: renewable energy source. produced from sugar cane, maize and yeast. starch and cellulose broken down by enzyme. fermenters make the optimum conditions. anaerobic respiration -> yeast. plant material turns to ethanol.
respiration:
3 main processes of ATP: muscle contractions, cell signalling and active transport.
molecules that can be used in respiration include, lipids, proteins and carbohydrates. proteins in very extreme cases and carbohydrates break up glycogen.
