Question
b. If [glucose] is greater outside the muscle cell than inside, what is the sign of AG for transport of the c. What is the value of Keg for the movement of glucose across the plasma membrane? d. What is the value of AG for movement of glucose into cells? e. Sketch a reaction progress curve for the movement of glucose into a muscle cell by facilitated glucose into the muscle cell? diffusion. Assume conditions in which [glucose] is greater outside of the cell. Label the axes. f. Sketch a kinetics curve for the movement of glucose into muscle cells by facilitated diffusion. Label the axes. Note that the X-axis may be labeled either "extracellular concentration" or "concentration gradient"Explanation / Answer
b.
The movement of molecules or ion up or down the concentration gradient involves the change in free energy ?G. The glucose in the given condition is moving down the concentration gradient than the sign for ?G will be negative as the energy release here.
c.
The ?Gº for the given condition is negative than the equilibrium constant (Keq) for the condition will be greater than 1.
d.
The sign of ?Gº is negative and the value at standard conditions is -1840 cal/mol.
