Given these parameters, what is the AG for K ion transport into the frog muscle cell in the presence of Ach? Dr. Knowsalot smiles and nods. "Good," she says. "Now let's see whether K+ ions pass through the open Ach receptors into the cell. As you might remember, these channels are permeable to Na+, K+, and Ca2+. For a typical frog muscle cell, the concentration of K+ is roughly 124 mM inside the cell and 2.30 mM outside the cell."...

In a copper-zinc voltaic cell, one half-cell consists of a ZnZn
electrode inserted in a solution of zinc sulfate and the other
half-cell consists of a CuCu electrode inserted in a copper sulfate
solution. These two half-cells are separated by a salt bridge.
At the zinc electrode (anode), ZnZn metal undergoes oxidation by
losing two electrons and enters the solution as Zn2+Zn2+ ions. The
oxidation half-cell reaction that takes place at the anode is
Zn(s)→Zn2+(aq)+2e−Zn(s)→Zn2+(aq)+2e−
The CuCu ions undergo reduction...
