Technically, Francium would be the most easily reduced metal, however most people don't consider it to due its radioactivity. Next up though is Cesium. Rubidium is more easily reduced then potassium, and cesium is more easily reduced then rubidium.
Iron is the most common magnetic metal, possessing ferromagnetic properties that allow it to attract other materials containing iron.
Glucose is the most common energy source in cellular respiration.
Phospholipids are the most common type of molecule present in bacterial cell membranes. They have a hydrophobic tail and a hydrophilic head, which allows them to form a lipid bilayer that makes up the cell membrane.
This metal is sodium (na); sodium chloride is NaCl.
In the most common dry cell, which is the alkaline battery, zinc is the metal that is oxidized. When the battery is in use, the zinc undergoes oxidation at the anode, releasing electrons and generating electrical energy.

The second most common metal in the Earth's crust is aluminum. It makes up about 8% of the Earth's crust by weight, following closely behind silicon, which is the most abundant metal.
The most common liquid metal known to man is Mercury. It is also often referred to as quicksilver. It is heavy and silvery-white in color.
