Ions in cells
Web17 mrt. 2009 · The original aim of the present review was to survey the types of ion pump found in plant cells and tissues, and to compare these with those found in animals. Its aims narrowed very considerably in writing. It now reviews ion transport processes in giant algal cells, and tries to assess progress towards understanding the mechanisms involved. Web22 jul. 2016 · These are the reactions: Half-cell A: F e F e X 3 + + 3 e X −. Half-cell B: F e X 3 + + 3 e X − F e. This increases the F e X 3 + concentration in half-cell A while decreasing the F e X 3 + concentration in half-cell B. This will continue until both half-cells have the same [ F e X 3 +]. So, we can also describe half-cell A as the anode ...
