Question
In glycolysis, a 6-carbon molcculc is converted to two 3-carbon molecules. If carbon 1 is the anomcric carbon of the 6-carbon moleculc, which of these original carbons compose glyceraldehyde-3-phosphate? A.Carbons 1-2-3 B.Carbons 2-3-4 C.Carbons 3-4-5 D.Carbons 4-5-6 7. The process by which liver cells take up lactate from blood and convcrt the lactate to pyruvate for making more glucose (gluconcogcncsis) is known as... A. The insulin response B.The Cori cycle C.The lactatc shuttle D.Reciprocal regulationExplanation / Answer
6) The oxidation state of anomeric carbon 1 is 2, so after glycolysis it will convert to keto group where as oxidation state of 5 is 1 so it remains link to hydroxy. So aldehydic group will be in skeleton made up of carbon (4,5,6). so Carbon 4-5-6 composes glyceraldehyde-3-phosphate.
7)The Cori cycle is the metabolic pathway in which lactate produced by anaerobic glycolysis in the muscles (blood) moves to the liver cell and is converted to glucose.
