The chemical reaction that occurs when straight hair is made permanent curly needs to be explained. Concept Introduction: Oxidation is defined as a process of the addition of oxygen or an increase in the oxidation state of a substance. In terms of electrons, oxidation is the process in which loss of electron/s takes place. Reduction may be defined as the process in which the addition of hydrogen or an electropositive element takes place to the substance. In terms of electrons, the reduction is the process in which a substance gains an electron.

need help please and thanks dont understand only need help with C-F Learning Goal: As discussed during the lecture, the enzyme HIV-1 reverse transcriptae (HIV-RT) plays a significant role for the HIV virus and is an important drug target. Assume a concentration [E] of 2.00 µM (i.e. 2.00 x 10-6 mol/l) for HIV-RT. Two potential drug molecules, D1 and D2, were identified, which form stable complexes with the HIV-RT. The dissociation constant of the complex ED1 formed by HIV-RT and the drug D1 is 1.00 nM (i.e. 1.00 x 10-9). The dissociation constant of the complex ED2 formed by HIV-RT and the drug D2 is 100 nM (i.e. 1.00 x 10-7). Part A - Difference in binding free eenergies Compute the difference in binding free energy (at a physiological temperature T=310 K) for the complexes. Provide the difference as a positive numerical expression with three significant figures in kJ/mol. The margin of error is 2%. Part B - Compare difference in free energy to the thermal…
