 How do cells release the energy from glucose?

 Cellular respiration only occurs in lungs cells  Disagree  Without oxygen cellular respiration cannot continue.  Disagree  The bread products that you eat are a result of alcoholic fermentation.  Agree

 The process of converting energy from food molecules through chemical reactions to produce molecules of ATP.  ATP are molecules that the cell can use for energy.

 Occurs in the mitochondria of both plant and animals.  Needs oxygen in order to take place.  Referred to as aerobic respiration.  Produces Carbon dioxide, water, and energy in the form of ATP  Most of the cells energy is made using this process.

 Where does cellular respiration occur?  What are the end products of cellular respiration?  Which product is used by the cell for energy?

 This is the process cells use to obtain energy when oxygen levels are low.  The process is called anaerobic “without oxygen”.  Fermentation occurs in the cytoplasm.  There are two types of fermentation Alcohol fermentation Lactic acid fermentation

 When would a cell use fermentation instead of cellular respiration?

 Alcohol fermentation Used in making bread, beer, wine Produces alcohol, carbon dioxide, and energy in the end.

 Lactic acid fermentation Produces lactic acid and energy  Some bacterial and fungi use this process in a making yogurt and cheese.  When you exercise your muscles use this process. The lactic acid that is produced can cause muscle cramps.

 Compare and contrast the difference between cellular respiration and fermentation?  How are the two fermentation processes different?
