Q

What does it mean if a process is anaerobic? Anaerobic does not need oxygen. Which part of cellular respiration is anaerobic?

Q

Name 2 types of fermentation

A

Lactic-acid Fermentation(follows glycolysis)

  1. Turns pyruvate into lactic acid
  2. Occurs in skeletal muscle during anaerobic exercise
  3. Used to make cheese,yogurt, sour cream

Alcoholic Fermentation

  1. Yeast and bacteria use this process
  2. Use pyruvate to make ethyl alcohol and carbon dioxide
  3. Use to make breads, beers, and wines

Q

Why do runners breathe heavily after a sprint race?

A

Could not take in enough oxygen while running

20
Q

Bread rises as a result of yeast fermentation. How might fermentation causes bread to rise?

A

fermentation gives off Carbon Dioxide and alcohol. Alcohol evaporates

21
