Flask A contains yeast cells in glucose-minimal salts broth incubated at 30C with aeration. Flask B contains yeast cells in a glucose-minimal salt broth incubated at 30C in an anaerobic jar.

-Which culture produced more ATP?
-Which culture had a shorter generation time?
-which culture had a greater cell mass?
-which culture produced more alcohol?

Instead of using yeast cells the same experiment was performed with Clostridium, an obligate anaerobe. Again flask A had aeration and Flask B was in an anaerobic jar.

-Which culture produced more ATP? (*aeration)
While both cultures can undergo glycolysis more ATP is produced in the presence of oxygen because the yeast cells can now utilize the Kreb cycle.

-Which culture had a shorter generation time? (*aeration)
While the division rate is constant for cells whether they ...

  • Fermentation for Carbohydrate Solutions

    Yeast have the enzyme, sucrase, which can split sucrose into its two monosaccharides. In addition, it can then utilize the released glucose and fructose. No problem there. Molasses has lots of sucrose in it so is readily fermentable by yeast.

  • Metabolic Rate and Gas Production

    The use of oxygen in the conversion of sugars to CO2 and water releases much more energy stored in sugar than fermentation does. It is about 16 times as much ATP is generated from fermentation of the same sugar.

  • Fermentation of beer

    After primary fermentation, the beer may be allowed a second fermentation, which allows further settling of yeast and other particulate matter "trub" which may have been introduced earlier in the process.

  • Fermentation after glycolis

    The cell can survive, for a while at least, even in the absence of oxygen. Whew! So, for fermentation in yeast, you want to feed them sugar, but in the absence of oxygen.

  • Cell Biology

    In the primary fermentation phase, the yeast must multiple and requires just a little bit of oxygen to get everything started, but very quickly one must cut off the oxygen supply to force the yeast into anaerobic respiration or fermentation so it can

  • anaerobic respiration in yeast

  • Alcohol Content Differences In Spirits And Beers

    The common denominator for all types of beverage alcohol is fermentation. Fermentation occurs whenever the two necessary ingredients, carbohydrate and yeast, are combined in a liquid.

  • Heat Created by Fermentation and Combustion of Glucose

  • Yeasts.

    Fermentation (anaerobic respiration) in yeast essentially amounts to glycolysis with a side-reaction for converting pyruvate into ethanol and carbon dioxide. This is done in order to reoxidize the NADH back to NAD+ so that glycolysis can continue.
