Anaerobic Respiration Mini Lab 1. Open and close your hand as many times as possible for 30 seconds. Have your partner time and record the results…QUICKLY! After only a 5 second break repeat this step for a total of 5 trials. 2. After you have completed the 5 trials. Switch jobs with your partner, and record your partner’s 5 trials. Trial 1 Trial 2 Trial 3 Trial 4 Trial 5 Name Name Observations: How did your hand feel after the 1st trial? 3rd trial? 5th trial? How did the amount of times you could open st and close your hand change from the 1 trial to the 5th trial? Analysis: Can you think of a time where your body got tired from working hard? Give an example. Why do you think your hand began feeling this way? Why do you think your muscles get sore during a hard work out? Key Terms: Aerobic– occurs with oxygen Anaerobic – occurs without oxygen Anaerobic Respiration Cellular Respiration Glycolysis ATP Anaerobic Alcohol Lactic Acid Fermentation Fermentation ATP ATP Fermentation NO O2 available! Some ATP made but not much There are two types of fermentation: 1. lactic acid fermentation 2. alcohol fermentation. Alcohol fermentation Used by bacteria and yeast (a type of fungus). Alcohol and CO2 are products of this reaction. Use yeast in brewing, winemaking and baking. The bubbles (CO ) 2 generated by baker’s yeast allow bread to rise. Lactic Acid Fermentation Lactic acid fermentation is used by certain fungi and bacteria in the dairy industry to make cheese and yogurt. Lactate is the product of this reaction. Lactic acid fermentation is also used by human muscles. Muscles make ATP by lactic acid fermentation when oxygen is scarce. As your muscles run out of oxygen, they need a quick way to make more ATP. Lactic acid fermentation provides the ATP but produces lactate which accumulates causing a burning sensation in the muscles. Soon after, the lactate is carried away by blood to the liver where it is converted back to pyruvate.
