Yeast are unicellular fungi that can perform aerobic respiration and fermentation. You place yeast in an environment without oxygen and measure their glucose consumption. When you move the yeast to an environment with oxygen, you observe that their consumption of glucose dramatically decreases. Explain this observation and your answer should include some numbers .
Homework Answers
yeast growing in anaerobic conditions converts glucose to pyruvate via glycolysis, then pyruvate is converted to ethanol and carbon dioxide by alcohol fermentation, the total number of ATP produced during this process is 2 ( net number of ATP produced via glycolysis is 2).
Yeast growing in aerobic conditions glucose is oxidised to Carbon dioxide and 36 ATPs are produced from a glucose molecule. so yeas growing in aerobic conditions use less glucose ( almost 18 times less glucose) than the yeast growing in anarerobic conditions,due to the difference in the number of ATPs produced from a glucose molecule in different conditions.

Exercise 7: Aerobic Respiration and Alcohol Fermentation 57 JUUUUUUUUUUUUU the magnesium ions, and they are no longer available to act as cofactors. Without its cofactor, an enzyme changes its three-dimensional form, and, as a result, has the shape of its active site altered. This enzyme's normal substrate will not be able to fit into this altered active site, and thus, the enzymatic reaction has been noncompetitively inhibited. If glycolysis is inhibited by NaF, fewer pyruvic acid molecules will be produced;...

n a reproduction of an experiment famously performed by Louis Pasteur, you cultured yeast in the absence of oxygen (anaerobic growth) and measured (1) the rate of cell division, (2) the rate of glucose consumption, and (3) the intracellular ATP:ADP ratio. You then moved the cells to an incubator containing normal atmosphere (i.e., 21% oxygen), completed a second set of measurements, and made the following observations: The rate of cell division increased considerably after the addition of oxygen (aerobic growth)...
