QUESTION 45 Which of the following is a catabolic process that takes place only in the absence of oxygen? O fermentation glycolysis electron transport / oxidative phosphorylation citric acid cycle QUESTION 46 Which of the following is the name of a metabolic pathway that uses glucose to produce ribose-5-phosphate and the reducing coenzyme, NADPH? oxidative deamination glycolysis the pentose phosphate pathway gluconeogenesis fermentation QUESTION 47
QUESTION 25 The citric acid cycle cannot function if o2 is not available; why is this OA. O2 is required for the redox reactions of the citric acid cycle. B. All of these answers are correct OC. The electron transport chain will not function without 02, thus the NAD+ and FAD needed for the citric acid cycle will not be regenerated. OD. None of these answers are correct O E 02 is the final electron acceptor of the citric acid...
