For cells that are capable of aerobic cellular respiration and fermentation, such as yeast cells, one pathway may be favored over the other in certain circumstances.  Which of the following accurately describes an advantage of the fermentation pathway, when compared to aerobic cellular respiration? a) Fermentation is less costly for the cell because it does not involve enzymes b) Fermentation generates a higher amoung of ATP per glucose substrate c) Fermentation is quicker because it does not involve glycolysis d)Fermentation can occur in the absence of oxygen (O2)

4. What is glycolysis? A) It is the conversion of acetyl-CoA into carbon dioxide with production of ATP and NADH B) It is the conversion of glucose into pyrHYic acid with production of ATP and NADH C) It is the conversion of pyruviç acid into glucose with production of ATP and NADH D) None of the above

the compound produced by the Calvin Benson cycle that so important to the maintenance of life on earth is a) water b) carbon dioxide c) oxygen d) glucose 2. cellular respiration refers to a) the diffusion of oxygen into the cells b) breathing  c) the transfer of O2 and CO2 across a cell membrane Carbon dioxide is to the Calvin Benson cycle is  a) oxaloacetic acid is to the electron transport system  b) pyruvic acid is to glycolysis  c) ATP is the electron transport system  d) acetyl co-enzyme A is to the Kreb's cycle  most of the atp produced in cellular respiration is associated with the a) formation of pyruvic acid b) krebs cycle c) formation of water d) production of alcohol  Both NAD and FAD are compounds derived from the B vitamins niacin and flavin. Which of the following would most likely be a symptom of a person whose diet is deficient in these vitamins. a) increase production of carbon dioxide b) a lack of energy c) increase production of water d) decrease oxygen production
