Mr. q wants to know why he has developed a fatty liver. you would give him all of the following reasons except: a. when the enzymes oxidize alcohol, they remove hydrogens and high energy electrons and attach them to the niacin coenzyme. b. the accumulation of the niacin coenzymes with their hydrogens and electrons slows down the tca cycle so that pyruvate and acetyl coa levels build up. c. the excess acetyl coa is used to make fatty acids, which accumulate as fat in the liver. d. the enzymes alcohol dehydrogenase and acetaldehyde dehydrogenase break down alcohol to acetyl coa. e. the excess acetyl coa is used to make ketogenic amino acids.

Which of the following statements regarding anfinsen's denaturing experiments with ribonuclease a (rnase a) are valid? exposing the denatured protein to air oxidation and then dialysis to remove urea restored the protein to its original functionality. removing urea by dialysis and then allowing air oxidation of the denatured protein restored the protein to its original functionality. denaturing the protein with both urea and β-mercaptoethanol yielded an inactive protein. anfinsen concluded that protein folding is determined by its primary sequence.

The tasmanian devil, a marsupial carnivore, is facing extinction due to devil facial tumor disease (dftd) which causes bulging cancerous lumps and lesions to erupt around the face and neck — often causing enough deformation to make seeing or eating difficult. dftd has evolved into a contagious cancer, a trait that is unique among cancers. devil mating behavior involves biting around the head and neck, allowing cells from one individual — especially cells from the crumbly dftd tumors — to be transferred to the wounds or face of a new individual. this marsupial was once found across australia, but sea levels rose, isolating the tasmanian population, while the australian population went extinct. what would be an outcome of genetic isolation that is likely to have impacted the spread of dftd? a) reduced territory puts diseased individuals in greater contact with non-diseased ones. b) inbreeding results in less variation in facial features so the cancer is generally fatal. c) genetic isolation has made it difficult for scientists to develop a vaccine against dftd. d) the lack of genetic variation in the immune system of tasmanian devils minimizes resistance to the disease.
