Question 9

Synthesis of sorbitol

Answer 9

Polyol Pathway

Question 10

Final common pathway for the aerobic oxidation of carbohydrates, lipids, and proteins

Answer 10

Tricaboxylic Acid Cycle

Question 11

Reduced coenzymes NADH and FADH2 each donate a pair of electrons to a specialized set of electron carriers

Answer 11

Electron Transport Chain

Question 12

Conversion of excess nitrogen into a non-toxic, highly water-soluble compound in humans

Answer 12

Urea Cycle

Question 13

Other name of the urea cycle

Answer 13

Krebs-Henseleit Cycle

Question 14

Synthesis of palmitate from acetyl CoA

Answer 14

Lipogenesis

Question 15

Breakdown of palmitate into acetyl CoA

Answer 15

Beta-oxidation

Question 16

Synthesis of alternative metabolic fuel from acetyl CoA during a fast

Answer 16

Ketogenesis

Question 17

Lactate in exercising muscle is converted back to glucose in the liver

Answer 17

Cori Cycle

Question 18

In muscle, pyruvate is transaminated to form alanine, which is shuttled to the liver where the amino group enters the urea cycle and the pyruvate is used to make glucose, which is shunted back to muscle

Answer 18

Glucose-Alanine Cycle

Question 19

Provides the glycerol backbone of triacylglycerol in liver and adipose tissue, and carbon skeleton of nonessential amino acids

Answer 19

Glycolysis

Question 20

Provides the energy required by gluconeogenesis

Answer 20

Beta-Oxidation

Question 21

Only two pathways present in erythrocytes

Answer 21

Anaerobic Glycolysis

Pentose Phosphate Pathway

Question 22

Reconvert purines obtained from diet and turnover of cellular nucleic acids to nucleoside triphosphates

Answer 22

Purine Salvage Pathway
