Discussion: The two dyes identified were disperse blue 3 and disperse red 9. Disperse red 9 separated first because it is less polar than disperse blue 3. This is due to the structure of disperse red 9 being more symmetrical than that of disperse blue 3 and having more nonpolar bonds. Disperse blue 3 is more polar because it has a hydroxide bond and has a larger dipole. The principle behind using column chromatography is that it separates compounds based on polarity. The alumina serves to allow

Muscle Contraction Tutorial/Review 1. Hydrolysis is the decomposition of a substance by the insertion of water molecules between certain of its bonds. The third phosphate is removed by hydrolysis and free energy is released. ADPneedds to have another phosphate molecule in order to become ATP and this happens through hydrolysis. This ATP can be used in the muscle contraction and relaxation. 2. When one flexes his/her arm‚ the muscle on top is the bicep. The origin of the bicep is at the tubercule

This calcium is then used to initiate contraction‚ given the affinity of troponin to calcium. As troponin attaches to calcium‚ it produces a movement of the tropomyosin molecule that frees up the actin site so that the charged cross-bridge can contact the site resulting in the liberation of energy
