Glucose are stored as glycogen in muscle cells, from which it
can again be mobilized during exercise.
a) Write down the partial reactions as well as the net yield for
the conversion of glucose-6-phosphate to glycogen and for the
conversion of glycogen to glucose-6-phosphate.
b) Calculate the energy required for the consumption of the total
process of converting glucose-6-phosphate to glycogen and back to
glucose-6-phosphate expressed as energy-rich phosphate bonds (ATP
equivalents).
ΔG0’ for the reaction: ATP + H2O → ADP + Pi = –30.5 kJ∙mol-1.
c) Calculate ΔG’ for the reaction at 25 °C and pH 7, when [ATP] = 5
mM, [ADP] = 0.5 mM and [Pi] = 1.0 mM.
Phosphocreatin constitutes a small extra storage of energy within
muscle cells, and is formed from phosphorylation of creatin. The
reaction is catalyzed by creatine kinase and ΔG0’ for the reaction
is +2.3 kJ∙mol-1 (progressing towared the formation of
phosphocreatin).
d) Calculate how much phosphocreatin formed relative to creatin at
equilibrium in the creatin kinase catalyzed reaction (assuming the
same temperature, pH and concentrations of ATP and ADP as indicated
in the previous question).

Electric Potential (Parallel Plate Capacitor Potential Energy and Potential)
A parallel plate capacitor has two terminals, one (+) and the other (-). When you move a test positive charge, q at uniform velocity from the negative terminal (Ui and Vi) to the positive terminal (Uf and Vf), work W = ΔU = qΔV is done on the charge, increasing the energy of the field by this amount. The work done by the field on the charge is – W. (V = U/q, all have their usual meaning)
QUESTIONS on the above observations:
(i) What is the work done to move a negative charge, q at uniform velocity from the positive to the negative terminal? Increasing the potential energy, a push (work) is needed to move the object.
(ii) Which terminal is the high potential for the plus charge?
(iii) Which terminal is the high potential for the negative charge?
(iv) If you do work 1.0 eV to move a proton from the negative to the positive terminal of a capacitor, how much work will you do to move an electron in the exact same manner from the positive the negative terminal of the same capacitor?
(v) What is the potential difference across the above capacitor?

Please explain how to solve and give me an answer.
14-3 Suppose you and most other investors expect the rate of inflation to be 7 percent next year, to fall to 5 percent during the following year, and then to remain at a rate of 3 percent thereafter. Assume that the real risk-free rate, r*, is 2 percent and that maturity risk premiums on Treasury securities rise from zero on very short-term bonds (those that mature in a few days) by 0.2 percentage points for each year to maturity, up to a limit of 1.0 percentage point on five-year or longer-term T-bonds. IBM warrants a DRP of 0.4% and a liquidity premium of 0%. a. Calculate the interest rate on one-, two-, three-, four-, five-, 10-, and 20-year Treasury securities and plot the yield curve. b. Now suppose IBM, a highly rated company, had bonds with the same maturities as the Treasury bonds. As an approximation, plot a yield curve for IBM on the same graph with the Treasury bond yield curve. (Hint: Think about the default risk premium on IBM’s long-term versus its short-term bonds.)

Consider the following statements: #include #include class Temporary { private: string description; double first; double second; public: Temporary(string = "", double = 0.0, double = 0.0); void set(string, double, double); double manipulate(); void get(string&, double&, double&); void setDescription(string); void setFirst(double); void setSecond(double); }; Write the definition of the member function set() so that the instance variables are set according to the parameters. Write the definition of the constructor so that it initializes the instance variables using the function set() Write the definition of the member function manipulate() that returns a decimal number (double) as follows: If the value of description is "rectangle", it returns first * second If the value of description is "circle" it returns the area of a circle with radius first if the value of description is "cylinder" it returns the volume of a cylinder with radius first and height second. HINT: the volume of a cylinder is simply the area of the circle at the base times the height. If the value of description is "sphere" it returns the volume of the sphere with radius first. Otherwise it returns -1.0; To save you googling what the formula for the volume of a sphere is, given the radius of the sphere, it is V=43πr3 HINT: was included for a reason for the manipulate() function.
