Which of the statements about the oxygen in the air we breathe is true? oxygen function as the final electron acceptor in the electron transport chain. It combines with hydrogen to form water. It combines with carbon to form CO_2, carbon dioxide, Both A and Bare true. Both A and C are true. In terms of the number of ATP molecules directly produced from glucose, the major energy-yielding cellular process is glycolysis. the citric acid cycle. gluconeogenesis. Ketene bodies are derived from fatty acids. glycerol. glucose amino acids. The conversion of glycogen to glucose to glucose-6-phosphateoocurs in the liver. the skeletal muscles. both A and Bare correct The conversion of glucose-6-phosphate to free glucose, which can be secreted into the blood, occurs in the liver. the skeletal muscles. both A and Bare correct The glucose from pyruvic acid (reverse of glycolysis), derived from lactic acid, amino acids or glycerol is called glycogenesis. glycogenolysis. glycolysis. gluconeogenesis. Which of the following organs has an almost absolute requirement for blood glucose as its energy source? liver brain skeletal muscles heart

Solution

19.D(BOTH A AND B ARE TRUE)

20.C(30-36 ATP)

21.A(FROM MOST OF FATTY ACIDS AND A LEAST AMOUNT OF AMINO ACIDS,TOO.)

22.C(BOTH A AND B ARE CORRECT)

23.A(LIVER IS ONLY ORGAN RESPONSIBLE FOR THAT PROCESS)

24.D(DEFINITION)

25.B(BRAIN NEEDS MORE ENERGY)
