It discusses electrochemistry, which converts chemical to electrical energy, seen in batteries. It highlights that direct redox reactions, like those between zinc and copper ions, require separation into oxidation and reduction to perform work in electrochemical cells. These cells feature a solution for reactions, a conductor for electron transfer, and a salt bridge for ion movement.

It describes the structure of cell membranes formed by phospholipids, highlighting their hydrophilic heads and hydrophobic tails that create a lipid bilayer. This bilayer acts as a barrier while enabling selective passage of substances through embedded proteins that assist in the movement of specific ions and molecules.
