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...

1. For metabolism in multicellular organisms to proceed efficiently, it is important that the final products be gases, water, or both. Why? To maintain metabolism in a steady state, there must be no possibility of a build–up of final products. The easiest disposal products are the multicellular organism’s universal solvent, gases, or both. 2. Look at the two starred reactions in the lesson just covered (the redox reactions involving NADH and O2). Compare the tendency of NADH to donate ...
