7. Isotopically labeled Mn(CH313C=O)(12CO)5 undergoes loss of carbon monoxide upon heating. Is 12CO or 13CO or a mixture of both formed? Why? What is the other product?
If the C-2 carbon of glucose were labeled with 14C, which if the carbons atoms in 3PG would be labeled during glycosis ? Give a numeric answer please .
If a molecule of glucose is labeled with 14C at position 1 proceeds through glycolysis, where will the radioactive label end up? a) At the carboxyl carbon of all the pyruvate produced b) At the carboxyl carbon of half of the pyruvate produced. c) At the methyl carbon of half of the pyruvate produced. d) At the methyl carbon of all the pyruvate produced. e) At the carbonyl carbon of all the pyruvate produced. f) At the carbonyl carbon of...
21. Glucose labeled with 14C in C-1 and C-4 gives rise in glycolysis to pyruvate labeled in: A) its methyl carbon B) all three carbons C) its carbonyl carbon D) its carboxyl carbon E) A and D
If glucose labeled with 14C at C-2 were metabolized in the liver, the first radioactive pyruvate formed would be labeled in (pick from list given below) i) all three carbons ii) its carbonyl carbon iii) its carboxyl carbon iv) its methyl carbon Ali B) ii C) iii D) iv E) A and C
Question: You buy a sample of glucose that has the radioactive carbon-14 (C) isotope at the second position (Carbon #2). All other carbon positions in the glucose molecules have the "C isotope. "C is only a label and does not alter the biochemical behavior of the molecules in which it is found. This glucose sample is mixed with all the enzymes derived from liver cells, which initially contain no other C-labeled chemicals. A) Draw the Haworth structure of glucose and...
Biochemistry: Answer the following questions about a molecule of glucose that has a radioactivr carbon at carbon 2. For each question, draw the molecule specified and indicate the location of the radioactive carbon. if there are multiple positions that the radioactive carbon may be located, include ALL positions in your answer. draw structure 2. Answer the following questions about a molecule of glucose that has a radioactive carbon (C14) at carbon 2. This molecule undergoes metabolism in a human cell...
Question #5 If glucose is labeled with "C at its C4 position, where will the label appear in pyruvate? DRAW pyruvate and CIRCLE the "C.
.) (3pts) If radioactive glucose labeled at carbon #6 with 14C, were incubated in a cell-free liver homogenate under anaerobic conditions, which carbon in the lactate produced would be labeled with 1℃ (refer to the carboxyl carbon of lactate as C1, the central carbon as C2, and the methyl carbon as C3)? What if theglucose were labeled at carbon #3 instead? In both cases, explain your answer. .) (3pts) If radioactive glucose labeled at carbon #6 with 14C, were incubated...
