Bell Ringer: 1.What is the difference between Aerobic and Anaerobic? 2.What is the balanced chemical equation for Cellular Respiration? 3.What are the three stages of Cellular Respiration? 4.How many ATP are need to start Glycolysis? 5.How many total (net) ATP are produced from 1 molecule of C 6 H 12 O 6 during the entire cellular respiration process ? 6.What is the process that occurs if oxygen is not present?

What if there is no oxygen? Then Fermentation occurs….. Fermentation releases the energy in glucose when oxygen is not available. Fermentation releases the energy in glucose when oxygen is not available. This is Anaerobic because it does not require oxygen. This is Anaerobic because it does not require oxygen. Two Types : Two Types : Alcoholic Fermentation Alcoholic Fermentation Lactic Acid Fermentation Lactic Acid Fermentation

Alcoholic Fermentation Performed by Yeast Performed by Yeast Uses pyruvic acid so that glycolysis can continue. Uses pyruvic acid so that glycolysis can continue. Converts Pyruvic acid into ethyl alcohol and carbon dioxide as waste. Converts Pyruvic acid into ethyl alcohol and carbon dioxide as waste.

Examples of Alcoholic Fermentation Bread dough Bread dough Beer and Wine Beer and Wine

Lactic Acid Fermentation Performed in the muscle cells of Animals. Performed in the muscle cells of Animals. Converts Pyruvic Acid into Lactic Acid so that glycolysis can continue. Converts Pyruvic Acid into Lactic Acid so that glycolysis can continue.

Example of Lactic Acid Fermentation During intense exercise, your body cannot supply oxygen to your muscles. This causes the muscles to begin Lactic Acid Fermentation in order to produce ATP. During intense exercise, your body cannot supply oxygen to your muscles. This causes the muscles to begin Lactic Acid Fermentation in order to produce ATP. The lactic acid builds up in your muscles causing you to feel sore. The lactic acid builds up in your muscles causing you to feel sore.

How do you get rid of the Lactic Acid build up in your muscles? When you breathe heavily after exercise, you are basically paying back on oxygen debt. When you breathe heavily after exercise, you are basically paying back on oxygen debt. Your blood stream eventually washes away the Lactic Acid into your liver to be digested. Your blood stream eventually washes away the Lactic Acid into your liver to be digested.

Energy and Exercise Three energy “tanks”: Three energy “tanks”: Stored Energy: ATP stored in cells supports around 6 seconds of intense activity. Stored Energy: ATP stored in cells supports around 6 seconds of intense activity. Lactic Acid Fermentation: can supply energy for about 90 seconds. Lactic Acid Fermentation: can supply energy for about 90 seconds. Cellular Respiration: After 90 seconds, this is the only way to obtain continuous ATP. The process is slow. This is why athletes must pace themselves. Cellular Respiration: After 90 seconds, this is the only way to obtain continuous ATP. The process is slow. This is why athletes must pace themselves.
