Water is split to yield two electrons, with oxygen and two hydrogen ions as by-products.
Explanation:
The electron lost from the reaction center is replaced with an electron that comes from water. When two water molecules are split, four electrons and four protons are released.
An amino acid is an organic molecule that is made up of a basic amino group (−NH2), an acidic carboxyl group (−COOH), and an organic R group (or side chain) that is unique to each amino acid.
