Textbook Question
Chapter 8.1, Problem 3CC
WHAT IF? → If you place a teaspoon of sugar in the bottom of a glass of water, it will dissolve completely over time. Left longer, eventually the water will disappear and the sugar crystals will reappear. Explain these observations in terms of entropy.

kcat = ?
an enzyme has an aspartic acid in the active site with a pKa = 4.0 and the kcat for this enzyme is directly proportional to the fraction of this side chain that is ionized. If the kcat at pH = 4.0 is 52.9x103 s-1 what is the kcat for this enzymes at pH 3.5
Which has greater conformational entropy, a folded protein, or an unfolded one? Actually can you please explain about conformational entropy??
Explain in detail how protein folding is a thermodynamically favored process even though the
change in entropy is highly unfavorable.

- Activity B: Molecules in Motion Brownian movement occurs when particles in a solution move because they are being struck by other particles in a solution. This was first discovered by Dr. Robert Brown in 1827 when he was observing pollen grains in water under a microscope. To observe this ourselves, we will look at carmine particles suspended in water under a microscope. a Brownian Motion Wetch later Share Watch on DYoulube Which statement best describes the movement of the particles?

- During the folding of a protein in a buffered aqueous solution, what happens to the entropy of the protein and the entropy of the water? The entropy of the protein decreases while the entropy of the water increases. Both the entropy of the protein and the entropy of the water increase. Both the entropy of the protein and the entropy of the water decrease. The entropy of the protein decreases while the entropy of the water remains constant.arrow_forwardExplain why entropy increases when a lipid bilayer forms from phospholipid molecules.arrow_forwardIn each of the three systems, determine the state of entropy (low or high) when comparing the first and second: i. the instant that a perfume bottle is sprayed compared with 30 seconds later, ii. an old 1950s car compared with a brand new car, and iii. a living cell compared with a dead cell. a. i. low, ii. high, iii. low b. i. low, ii. high, iii. high c. i. high, ii. low, iii. high d. i. high, ii. low, iii. lowarrow_forward
