Propose a mechanism for this two step process using water and acidic/basic groups on the enzyme as needed (think NAC and NAS) OOC COO S- CoA. CH H20 O -C HO O -C CH citrate synthase CH CH2...
18. The carbon atoms of glutamate can enter the citric acid cycle after transamination to the corresponding a-keto acid (see question #7). When [a-14C]-glutamate undergoes transamination, what is the labeling pattern (if any) in the succinate generated immediately from the labeled glutamate? A. 2014C-CH=CHCOO is produced from la calutamate A. None, OOC-CH2-CH2-COO is produced from [a-14C]-glutamate B. 0014C-CH=14CH-COO is produced from [a-14C]-glutamate C. OOC-14CH2-14CH2-COO is produced from [a-14C]-glutamate D. 0014C-CH2-CH2-14COO is produced from [a-14C]-glutamate E. OOC-14C0-14CH2-COO is produced from [a-14C]-glutamate
