9:08 PM Figure 25-1 The TCA Cyele Use Figure 25-1 to answer the following questions Identify the molecule labeled "2 and 3." ONADH, CO O hydrogen atoms Ocitric acid, FADH2 O FADH2, NADH O carbon dioxide, NADH QUESTION 10 1 po During B-oxidation, what happens to the FADH2 and NADH that are oxidized from the fatty acid chain? O FADH2 and NADH enter glycolysis. O FADH2 and NADH enter the citric acid cycle. O FADH2 and NADH enter the electron transport chairn. OFADH2 and NADH enter substrate-level phosphorylation. UESTION 11 All of the following occur during the postabsorptive state, except that glycogenolysis occurs in the liver O gluconeogenesis occurs in the liver O levels of blood glucose are elevated. O fat mobilization occurs O ketone bodies may be formed UESTION 12 ransamination results in an ammonia-containing product that can be eliminated by the kidneys in the urine called creatinine bilirubin bicarbonate ion.

Explanation / Answer

10. Option 3rd is correct. FADH2 and NADH enters to the electron transport chain and provide electron to the chain. The transportation of electrons through electron chain release energy which is used to develop proton gradient. The proton gradient provide energy in the synthesis of ATP via ATP synthase.

11. Option 3rd is correct. Level of blood glucose increases only during absorption of carbohydrates into blood circulation. Once the absorption process is over, the glucose level cannot increase. Although glycogenolysis and gluconeogenesis occurs during lack of glucose but the end product of glycogenolysis or gluconeogenesis is not glucose rather glucose phosphate which act as an intermediate of glycolytic pathway.
