生化一答案（Biochemistry one answer） Biochemistry test paper (1), refer to the answer Noun explanation 5*4 1. gluconeogenesis: the process of converting non sugar substances into glucose or glycogen (3 points). The relative concentration of blood sugar is maintained mainly during fasting and starvation, and is carried out in the liver and kidneys. (1 points) 2.: DNA semiconservative replication of Okazaki fragments, lagging strand discontinuous synthesis of DNA fragments called Okazaki fragments. 3. beta oxidation: fatty acyl coenzyme A in mitochondria through repeated dehydrogenation, water, dehydrogenation, sulfur hydrolysis four steps, and finally all the acetyl coenzyme A. Because oxidation occurs on beta - carbon atoms, it is called beta - oxidation. 4. biotransformation: the transformation of non nutrients in the body by metabolic processes that increase their polarity in order to flow with bile or urine. Mainly in the liver. 5. fixed acid: sugar, fat and protein in the body produced by decomposition of lactic acid, sulfuric acid, phosphoric acid, acetoacetate, (2) not by the lung breath, only after the kidney with the urine is called fixed acid. (2) Fill in the blanks (1 cents per room, 25 points) 1. products of deamination of amino acids are ammonia and alpha keto acids. 2., the process of synthesizing DNA under the guidance of RNA is called reverse transcription. 3. unconjugated bilirubin in liver cells by glucuronyl transferase catalyzed into conjugated bilirubin, and with bile drained to the intestines, and the role of intestinal bacteria into urobilinogen, mainly excreted in the stool. 4. the role of the lung in the maintenance of acid-base balance is mainly to regulate the content of plasma carbonic acid by respiration, so as to maintain the ratio of sodium bicarbonate to carbonic acid. 5., the cell membrane is bounded, the body fluid can be divided into two parts: the intracellular fluid and the extracellular fluid. The end product of the 6. purine base in v
