A molecule is said to be reduced when one of its atoms gains an electron. Since electrons are negatively charged, the net charge of the molecule is reduced when one of it's atoms acquires an electron.
The molecule that becomes oxidized is simply gaining oxygen molecules. (The amount will vary between different molecules because of their different bonding capacities)
It loses an electron.
It loses electrons. LEO - OEL.

It will be NADH. An electron quarrier in the photosynthesis process.
Reduced... NADH
Nothing "happens to it" unless something happens to it. In other words, your question is missing the "when" part ("what happens to a molecule of protein WHEN ..."). Even then, it depends on the details; different proteins react in different ways.
When light strikes a chlorophyll molecule, electrons in the chloroplast get excited.

Chemically, reduced means that electrons are taken on to the molecule or atom. Opposite of oxidation; stripping of electrons.
What happens to the quick return ratio when the stroke length is reduced?

When the pressure of a gas is reduced it gets colder.
