Stage 2 of the urea cycle involves transport of citrulline to cytosol condensation reaction All of the listed answers argininocuccinate sythetase In the forth stage of the urea cycle O urea produced ornithine regenerated all answers provided water is the source of the oxygen atom How much energy is used or produced during the urea cycle? equivalent of 4 ATP made 4 APT made and 4 ATP used None of the provided answers o equivalent of 4 ATP used The...
Write the overall reaction for Step 6 of the TCA cycle (succinate -> fumarate), showing structures for succinate and fumarate. What other molecule is involved in Step 6 and what is it converted to (acronyms are fine)? What type of bonds are breaking and what type is forming in Step 6? How do you know that carbon is being oxidized in this step?
What are the substrates for arginase and CPSI in regards to the urea cycle? Also, what are the products of the reactions that arginase and CPSI catalyze? What cell type is CPSI expressed in?
13. Show the structures of reactants and products for the arginase reaction in the urea cycle. Name the two substrates that feed the two N atoms found in the final urea product into the urea cycle. (20 pts)
why are glutamine levels elevated in urea cycle deficiencies?
Which of the following is correct and most accurately describes the complete urea cycle of the eukaryotic cell? Choose one:A. The urea cycle occurs completely within the cytoplasm of the eukaryotic cell.B. The urea cycle occurs between the inner mitochondrial membrane and the matrix of the eukaryotic cell.C. The urea cycle occurs between the mitochondrial matrix and the cytoplasm of the eukaryotic cell.D. The urea cycle occurs completely within the mitochondrial matrix of the eukaryotic cell. Part 2 (1 point)...
he Urea cycle and Citric Acid cycle have two molecules that are shared. Describe these two metabolites and which enzymes use them.
Starting with glutamate, calculate the ATP expense/payout for (1) detoxifying the nitrogen through the urea cycle, (2) regenerating aspartic acid from the urea cycle products, and (3) the complete net oxidation of the alpha keto acid that results from the deamidation of glutamic acid. Please list each enzyme that is part of this calculation (no structures needed)
