Answer #1

ANS)

Electron transport chain comprises of 4 diverse edifices inside which electrons are exchanged successively starting with one then onto the next. The remainder of the protein complex is increasingly electronegative when contrasted with the underlying ones in light of the fact that in the end, the electrons need to achieve the last complex. So, To accommodate the electron exchange successively, the last protein complex holds the more electron pulling in power and in this manner is progressively electronegative.

    The electron transport chain consists of protein complexes embedded in the inner mitochondrial membrane, where it generat a proton gradient by a series of oxidation-reduction, or redox, reactions. Although all of the stages of cellular respiration (glycolysis, the citric acid cycle, and the electron transport chain) are necessary for life, the electron transport chain is sometimes called the most important stage. First complete the sentence, then answer the question. The electron transport chain uses the transfer of protons between protein...

    5. In an equilibrium denaturation experiment, one makes up a series of different protein solutions, 1, 2, ..., M, having different amounts of urea, a denaturing agent, x1, x2, ..., XM. Then, for each particular solution, having denaturing agent in amount x, one measures the proportion f(x) of native protein molecules and the proportion fo(x) = 1 - fr of denatured protein molecules. Increasing the denaturing agent increases the population of Drelative to N. In the absence of denaturing agent,...

    5. A stu dent isolated a protein and assumed it was made up of a single polypeptide. However, after treating it with excess dithiothreitol (DTT; see structure below), two polypeptides were obtained. One of the polypeptides contained 78 amino acids and the other contained 125 amino acids. Both polypeptides contained 1 Qys and 1 Met. A. Using the structure of DIT below, sketch what the protein likely looked like before treatment with DTT (label/name any key amino acids and the...
