BCH4024 060925 OC Su25 E1 Q4: The basic chemical unit in a cell include amino acids, monosaccharides and nucleotides. Monomeric units interact by covalent bonds to build macromolecules; these macromolecules interact to generate supramolecular complexes. What property distinguishes a supramolecular complex from a macromolecule.

BCH4024 060925 OC Su25 E1 Q48: Fatty acids (FAs) and Triacylglycerols (TAGs) are classes of lipids that play an important role in energy storage in eukaryotic organisms. The hydrocarbon chain in the tail region of both FA and TAG can be saturated or unsaturated. The degree of saturation will determine their melting point. Which statement about TAG and FA is correct?

BCH4024 060925 OC Su25 E1 Q50: Glycosphingolipids are a class of lipids with one, two or several glycans attached to a ceramide group. The regulation of these glycans on the head group of the lipid is important to the homeostasis of the cell. Which of the following best explains the accumulation of GM2 ganglioside in Tay-Sachs disease?

BCH4024 060925 OC Su25 E1 Q20: In the Anfinsen experiment, what major conclusion was deduced about protein folding?

BCH4024 060925 OC Su25 E1 Q40: Which enzyme regulation mechanism would convert a sigmoidal plot of Vo versus [S] to a hyperbolic plot in the presence of a heterotrophic allosteric enzyme?
