Teacher: Mirtha Ramirez Anaerobic respiration G9- Part 1 Anaerobic respiration in animals Oxygen debt – pay off The oxygen debt caused by anaerobic respiration is paid off during the recovery period after exercise. It is the oxygen needed to get rid of lactic acid that pays back the oxygen debt. lactic carbon acid oxygen dioxide water oxygen to pay back ‘oxygen debt’ Anaerobic respiration in microorganism and some plants Some plants and Yeast cells can respire without oxygen glucose Carbon dioxide + Alcohol (ethanol) This is a fermentation and is used in the brewing industry. Anaerobic respiration happens in microorganisms such as bacteria because they need to release energy from glucose too. Yeast, which are unicellular fungi, and bacteria can carry out an anaerobic process called fermentation https://biologywise.com/anaerobic-bacte The ethanol (alcohol) is useful for brewers and wine-makers, and the carbon dioxide is useful to bakers because it helps their bread rise. https://www.youtube.com/watch?v=eksagPy5tmQ https://www.youtube.com/watch?v=YbdkbCU20_M Aerobic and anaerobic respiration comparison Aerobic Anaerobic Needs Yes No oxygen?
