ANAEROBIC RESPIRATION Cellular Respiration WITHOUT oxygen Cellular Respiration
ANAEROBIC RESPIRATION Cellular Respiration WITHOUT oxygen
Cellular Respiration Recall that Cellular Respiration REQUIRES OXYGEN as one of its reactants But what happens when ATP is needed and there is NO OXYGEN available? Do you DIE? !?
Anaerobic Respiration Aerobic – “with oxygen” AIRobic Anaerobic – “without oxygen” Anaerobic respiration happens when there is no oxygen available. Does NOT make much ATP but it does happen VERY FAST!! It is NOT the method we want to use…but it will keep us alive Two types of anaerobic respiration: Alcoholic fermentation Lactic Acid fermentation
AEROBIC RESPIRATION AEROBIC Respiration uses oxygen and produces a LOT of ATP 36 ATP for every glucose molecule ANAEROBIC Respiration does not use oxygen and only produces a LITTLE ATP 2 ATP for every glucose molecule
Types of Anaerobic Respiration There are 2 types of ANAEROBIC respiration The type that is done depends on the type of organism doing the respiration Alcoholic fermentation – yeasts and other microorganisms Produces alcohol and CO 2 Lactic Acid fermentation – animals, like humans Produces lactic acid and CO 2
Alcoholic fermentation Done by yeast and other microorganisms Produces alcohol and CO 2 as waste products Bread is made this way Bread Making Video http: //www. youtube. com/watch? v=g. YXj. URc. Bk 98
Alcohol…Harmful or Not? !? YOU decide!!
The yeast are using the sugar to make ATP through ANAEROBIC respiration The balloon fills up with CO 2, which is a waste product
The holes in Bread are caused by pockets of CO 2, as a result of anaerobic respiration
Lactic Acid fermentation ■ Done by animals, like humans ■Produces lactic acid and CO 2 as waste products ▫Lactic acid builds up in the muscles and causes pain You’ve heard the saying… “Feel the Burn!!” The burn is caused by the acid building up in your muscles. Ouch
