UNE Medical Biochemistry Midterm Review Already Graded A A family presents for genetic counseling. The couple has two female children who are alive and well; however, their infant son recently died in the nursery with severe hemolysis (lysis of red blood cells) and jaundice. The wife recalls she lost a brother in infancy with severe hemolysis, induced after a viral infection. The physician suspects a glucose-6-phosphate dehydrogenase deficiency, this would result in a deficiency in which of the...

Fatty Acids from adipose tissue d. Dietary Glucose - Dietary Glucose What enzyme controls the synthesis of Malonyl CoA during fatty acid synthesis if Evelyn eats a fat...

How is malonyl-CoA formed? correct answer: Carboxylation of acetyl-CoA to form malonyl-CoA requires two steps (both use acetyl-CoA carboxylase). 1. The enzyme, complexed with biotin, acquires CO2 from HCO3 - a. Requires 1 ATP 2. The carbon is transferred to acetyl-CoA to form malonyl-CoA The overall reaction is irreversible and commits the molecule to fatty acid synthesis. Phosphate is added to HCO3 - and then removed so that biotin-carboxylase can grab the carbon. The carbon is donated to...
