UNE medical biochem FINAL |108 Questions | With Complete Solutions. Which of the following urea cycle enzymes catalyzes the reaction hydrolyzing the release of urea from arginine? Arginase Arginase releases urea from arginine through a hydrolytic cleavage. Which of the following enzymes is likely to be active in both the fed and fasted states? Glutaminase Glutaminase in the liver is responsible for freeing ammonia from glutamine. In the fasted state, glutamine will be in excess due t...

True or False: The majority of reactions of the urea cycle occur in the cytosol. - ANS true True or False: FADH2 yields 2.5 ATP molecules after donating electrons and hydrogen atoms to the electron transfer chain (ETC). - ANS False True or False: ATP is invested in the urea cycle. - ANS True True or False: There are five complexes associated with the ETC. - ANS False True or False: In the production of ATP via ATP synthase, the H+ ions move from the mitochondrial matrix to the in...

T/F the majority of reactions of the urea cycle occur in the cytosol true T/F NADH yields 1.5 ATP molecules after donating electrons and hydrogen atoms to the electron transport chain (ETC) false T/F GTP is invested in the urea cycle false T/F there are six complexes associated with the ETC false T/F in the production of ATP via ATP synthase, the H+ ions move from the mitochondrial matrix to the intermembrane space...

one gene-one enzyme hypothesis - each gene contains the information needed to make an enzyme What did George Beadle and Edward Tatum research? - Relationship between genes and proteins using the Neurospora Crassa One gene-one enzyme hypothosis (Neuroposa Example) - Neurospora can grow well on minimal medium (simple sugar, vitamins, inorganic salts), and therefore it must have enzymes produced by a certain gene that that transform these materials into amino acids and vitamins needed for gro...

"Initiation" of protein tranlsation is activated by ATP hydrolysis. T/F?False; GTP hydrolysis after addition of an aa, where does the aminoacyl tRNA now bind to?30S ribosomal RNA (small one) after citrulline is produced and in the cytoplasm what happens next in the urea cycle?citrulline is combined with aspartate to make arginosuccinate which is then split into fumarate (which leaves to enter TCA) and arginine. Arginine is then converted to Ornithine (via arginase) giving off Urea which ...
