Both A and B are correct All of the above are correct - correct answer-Both A and B are correct In simple diffusion a solute Is propelled by random molecular motion Moves up its concentration gradient Moves across a membrane because of an input of free energy. Both A and B are correct All of the above are correct - correct answer-Is propelled by random molecular motion The recycling rate of triacylglycerols to fatty acids is inhibited by Epinephrine Norepinephrine Insulin Lypase A and B - correct answer-Insulin The benzene ring of the aromatic amino acids is formed by the Dehydrogenation of cyclohexane Deamination of dietary phenylalanine Shikimate pathway Dehydroxylation of tyrosine Transamination of a-keto-b-methylvalerate - correct answer- Shikimate pathway Energy requiring transport mechanisms include Primary active transport Diffusion Facilitated diffusion Both A and B are correct Both A and C are correct - correct answer-Primary active transport Prostaglandins are involved in _________. Ovulation Inflammation Digestion Both A and B are correct All of the above are correct - correct answer-All of the above are correct Inorganic nitrogen is initially assimilated into which of the following amino acids Glycine Alanine Serine Glutamine Leucine - correct answer-Glutamine Why do most naturally occurring fatty acids have cis double bonds in them? The cis double bond introduces a kink in the chain. The cis double bond remains results in relatively no change in the fatty acid direction. The double bond results in a bend in the molecule elevating the melting point of the molecule. The double bond results in a bend in the molecule lowering the melting point of the molecule. none of the above - correct answer-The double bond results in a bend in the molecule lowering the melting point of the molecule.
