Reduction
Oxygen is reduced, gaining electrons and hydrogen ions
Sunlight excites electrons in chlorophyll during the process of photosynthesis, where they are used to convert carbon dioxide and water into glucose and oxygen. This excitation of electrons is a key step in converting light energy into chemical energy that the plant can use for growth and metabolism.
During photosynthesis and cellular respiration, oxygen is converted to water.
broken and recreated or mixed with other chemicals
They are called valence electrons, and they are responsible for an atom's chemical properties. During a chemical reaction, the valence electrons are the only part of an atom that participates.
Simply, reduction is the gaining of electrons and oxidation is the donating of electrons.

During cellular respiration, the substrate is oxidized by losing electrons and reduced by gaining electrons in a series of redox reactions.
The process of electron gain is called reduction. For example, if Br gains an electron, its oxidation number is reduced from 0 to -1, and will be written as Br-. The opposite of this (electron loss) would be called oxidation, or ionization.

Metabolism can speed up during adolescence. This is one of the times during a life cycle where the metabolism works faster.

Non metals generally form anions. They gain electrons during ionic bonding.
NADH is a reduced form of NAD and carries electrons during cellular respiration to produce energy. NAD acts as an electron carrier in metabolic reactions, accepting electrons to become NADH.
Molecules that furnish electrons during a chemical reaction are called reducing agents or electron donors. These molecules undergo oxidation as they donate electrons to another molecule, known as the oxidizing agent or electron acceptor.
