Homework Answers
In anaerobic respiration
(which occurs during
fermentation), less energy is
extracted (only 2 ATP
molecules per glucose
molecule) because the
products of the process,
such as ethanol, contain
more energy than does
carbon dioxide, the product
of aerobic respiration. In
muscle, the product of
anaerobic respiration is
lactic acid. In yeast, it is
ethanol.
No,aerobic yeast can not produce ethanol because it is alcoholic fermentation which occurs only in the absence of the oxygen.

1st attempt How do fermentation reactions in oxygen-starved muscle cells and anaerobically grown yeast cells differ? Choose one: Fermentation in muscle cells regenerates NAD and in yeast regenerates glucose. Fermentation in muscle cells generates NAD and in yeast generates NADH. Fermentation in muscle cells produces lactate and in yeast produces ethanol plus CO2. Fermentation in muscle cells produces ethanol plus CO2 and in yeast produces lactate. Fermentation in yeast cells includes glycolysis, whereas in muscle cells it bypasses glycolysis.

In a "pulse chase" experiment under anaerobic conditions, 14C glucose is added to an ethanol-producing yeast cell extract just long enough that each intermediate in the ethanol fermentation is labeled with a 14C (pulse). The 14C label is then diluted so that no additional radioactivity is incorporated into the intermediates (chase). 1. What position in ethanol will be labeled with 14C if 14C-glucose labeled at position C-1 is used? 2. Where should the 14C label sit in glucose for it...

Which of the following statements best describes the difference between aerobic and anaerobic metabolism? Check all that apply. - Anaerobic metabolism produces more ATP than aerobic metabolism. - Anaerobic metabolism produces less ATP than aerobic metabolism. - Only aerobic metabolism can occur in the absence of oxygen. - Anaerobic metabolism does not produce lactate while aerobic metabolism does. - Both anaerobic and aerobic metabolism run through glycolysis, Krebs cycle, and the electron transport chain. - Only anaerobic metabolism can occur...

2. Is there a difference between the fermentation rate of the yeast and the top the fermentation rate of the yeast and the temperature? Why? 3. Why do you need to incubate the yeast before you start monitoring air pressure? 4. What else do you think is being produced by yeast fermentation besides CO2? 5. Could you use a pressure sensor to measure aerobic respiration in yeast? Why?
