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.

The second law of thermodynamics, in a very general sense, states that entropy (S) is always increasing.

When phospholipids are dispersed in an aqueous solution, they will often form more ordered structures in the form of micelles, liposomes, or lipid bilayers. This behavior
seemingly contradicts the second law of thermodynamics. Why is this behavior in agreement with the second law of thermodynamics?
Liposome
Micelle

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

Consider a uniport system where a carrier protein transports an uncharged substance A across a cell membrane. Suppose that at a certain ratio of [A] inside to [A] outside, the AG for the transport of substance A from outside the cell to the inside, What is the ratio of the concentration of substance A inside the cell to the concentration outside? [A]inside [A] outside -81.28 Incorrect Answer Choose the true statement about the transport of A under the conditions described. Decreasing the concentration of the uniport protein in the membrane will cause AG to become a smaller positive number. Because AG is positive, the ratio [A] inside/[A] outside must be less than one. Increasing [A] outside will cause AG for movement of Aoutside to Ainside to become a larger positive number. Movement of Ainside to Aoutside will be spontaneous.

- The movement of energy between living organisms is a matter of atoms, molecules and compounds being built into larger molecules or being broke into smaller ones. Reviewing the two equations for energy transference, which one is building energy? 6CO2 + 6H2O + energy --------> C6H12O6 + 6O2 C6H12O6 + 6O2 ---------> 6CO2 + 6H2O + energyarrow_forwardFill in the blanks: In energetically coupled reactions, a [anabolic or catabolic] or [endergonic or exergonic] reaction, which breaks down large molecules into smaller ones, usually provides the energy to drive an [catabolic or anabolic] or [exergonic or endergonic] reaction, which creates large molecules from smaller ones.arrow_forwardIn a transition state diagram, which of the following are features of the transition state (TS)? There may be more than one correct answer, select all that apply. The change in energy in ground state to the transition state represents the Gibbs Free Energy If the reaction is reversible, the TS will only progress forward to form products The TS occupies a trough The TS is associated with the highest energy The TS occupies the highest peakarrow_forward
