REACTIONS & ENZYMES REACTIONS AND ENZYMES Table of Contents Endergonic and exergonic Energy releasing processes, ones that 'generate' energy, are termed exergonic reactions. Reactions that require energy to initiate the reaction are known as endergonic reactions. All natural processes tend to proceed in such a direction that the disorder or randomness of the universe increases (the ). Time-energy graphs of an exergonic reaction (top) and endergonic reaction (bottom).

Oxidation/Reduction Biochemical reactions in living organisms are essentially energy transfers. Often they occur together, 'linked', in what are referred to as oxidation/reduction reactions.

Is the gain of an electron. Alice In Chains Download Dirt there. Sometimes we also have H ions along for the ride, so reduction also becomes the gain of H. Gbxperience Anthems Vol 1 Free Download. Is the loss of an electron (or hydrogen). In oxidation/reduction reactions, one chemical is oxidized, and its electrons are passed (like a hot potato) to another (reduced, then) chemical. Such coupled reactions are referred to as redox reactions.

The metabolic processes,, and involve the transfer of electrons (at varying energy states) by redox reactions. Passage of electrons from compound A to compound B. When A loses its electrons it is oxidized; when B gains the electrons it is reduced.
