How does SDS denature hexokinase II during gel electrophoresis? SDS neutralizes charges on amino acids R-groups, disrupting hydrophilic interactions SDS cleaves disulfide bonds, separating the dimer into monomers SDS coats the protein with a negative charge, disrupting hydrophobic interactions SDS replaces hydrogen bonds with covalent bonds, stabilizing the unfolded protein

Exercise 2: (12 marks) 1. Consider a thin uniform circular disc of radius a and mass m in the (xy) plane. Calculate the moments of inertia of this disc, for the central, or symmetry, axis. Calculate the moments of inertia $I_x$ and $I_y$ using the perpendicular-axis theorem. 2. A thin uniform rectangular plate (lamina) is of mass 2 kg and dimensions 1 m by 2 m. Choose a coordinate system Oxyz such that the plate lies in the xy plane with origin at a corner, the long dimension a being along the x-axis. Find the following: (a) The moments of inertia tensor (b) The angular momentum about the origin if the plate is spinning with angular rate 10 rad s$^{-1}$ about the z-axis.
