Which of the following statements is false concerning the sedimentation coefficient (S) of a large molecule? Larger particle specific volumes tend to lower the sedimentation coefficient. Larger particle mass results in larger S values. Smaller and lighter molecules sediment faster during centrifugation through a dense fluid. The sedimentaion coefficients of the parts of a molecular complex do not necessarily add up to that of the fully assembled complex. It is proportional to the rate of sedimentation during centrifugation through a dense fluid.

- The sedimentation coefficient is a measure of how fast a particle sediments in a centrifugal field. It is influenced by the mass, shape, and density of the particle, as well as the density and viscosity of the medium. Show more…

Which of the following statements about collagen is FALSE? Tropocollagen is the basic structural unit. There is about 33% glycine in collagen. Both intramolecular and intermolecular crosslinks help stabilize the collagen fibrils. Hydroxylation of prolines occurs prior to collagen synthesis at the ribosomes. Collagen is a very strong protein and water insoluble.

Which statement is false? All of these statements are true. SDS coats the proteins with a uniform negative charge. When a protein sample containing SDS is heated, the SDS molecules bind to the proteins and cause them to denature. Proteins treated with SDS have a similar shape and charge-to-mass ratio. When a protein sample containing SDS is heated, the SDS molecules bind the proteins and cause them to fold into their native state.

Identify the incorrect statement/s. (a) The equivalent mass of $\mathrm{KMnO}_{4}$ in alkaline medium is one third of its molecular mass. (b) The mass of oxalic acid dihydrate required to prepare $500 \mathrm{~mL}$ of $0.02 \mathrm{~N}$ solution is $6.3 \mathrm{~g} .$ (c) The volume of $0.1 \mathrm{M} \mathrm{K}_{2} \mathrm{Cr}_{2} \mathrm{O}_{7}$ solution required to oxidise $35 \mathrm{~mL}$ of $0.5-\mathrm{M} \mathrm{FeSO}_{4}$ solution-in acidic medium is $29.17 \mathrm{~mL}$ (d) Phenolphthalein can be used as an indicator in iodometry.
