Homework Answers
Answer is sulfate and nitrate.
In anaerobic respiration ATP is produced without using oxygen and it still constitute electron transport chain system. Unlike, aerobic respiration it doesn't use oxygen as final electron acceptor rather it uses nitrate, sulfate, or sulphur. The protien complex such as nitrate reductase reduces nitrate into nitrite.

Select ALL of the statements that correctly describe the Krebs cycle. A. Pyruvic acid must be converted to acetyl CoA prior to entering the cycle B. The molecule oxaloacetic acid picks up the acetyl group from acetylCoA, and in the last step of the cycle, oxaloacetic acid is regenerated. C.

Categorize the following: Aerobic respiration, Anaerobic respiration, Fermentation, None of these .Assume in all cases that these processes follow breakdown of glucose by glycolysis. Results in complete oxidation of glucose to CO2 Involves regeneration of reduced co-factors (e.g. regenerating NAD+ from NADH) Generates energy by substrate level phosphorylation only Generates ATP by oxidative phosphorylation Utilizes an electron transport chain Uses molecules such as NO3 - , SO4 2- , or Fe3+ as terminal electron acceptors Products include organic acids, alcohols,...
