Describe the function of the E1, E2, and E3 enzymes in the ubiquitinating system. Why are there ~500 E3 genes in the human genome but only two E1 genes? correct answers E1 enzymes attached ubiquitin to E2 enzymes, E2 enzymes conjugate ubiquitin to target proteins, and E3 enzymes recognize target proteins and facilitate ubiquitination by interacting directly with E2-ubiquitin and the target protein. E3 proteins must recognize a large number of target proteins, and thus there are hundreds of diffe...

true - Answer T/F: The majority of the reactions of the urea cycle occur in the cytosol. false - Answer T/F: The majority of the reactions of the urea cycle occur in the mitochondrial matrix. false - Answer T/F: FADH2 yields 2.5 ATP molecules after donating electrons and hydrogen atoms to the ETC. 2.5 ATP per NADH - Answer How many ATP molecules does NADH yield after donating electrons and hydrogen atoms to the electron transfer chain (ETC)? 1.5 ATP per FADH2 - Answer How m...

- urea cycle - liver - mitochondria and cytosol - urea Correct Answer-How does the human body deal with toxic ammonia released from the degradation of amino acids? - pathway name? - where does it happen? organ specific? - organelle-specific? - end-product? - CO2 (product of TCA cycle) used in 1st step of urea cycle - FUMARATE produced in cytoplasm during urea cycle is an intermediate of TCA cycle - citrulline reacts with ASPARTATE which can be from oxaloacetate of TCA cycle Correc...

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...
