Redox Reactions
The Principle of Redox
Chemical reaction that transfer electrons between reactants are called oxidation-reduction reactions, or redox reactions
IN redox reactions, the loss of electrons from a substance is called oxidation
The addition of electrons to a substance is called reduction = the amount of positive charge is reduced
Organic Fuel Molecules
During this, fuel molecules are oxidized, and O2 is reduced. Organic molecules with an abundance of hydrogen are excellent source of high-energy electrons
Energy Harvest via NAD+
Glucose and other organic molecules are oxidized in s series of steps. Every electron travels with a proton as a hydrogen atom. They are usually first passed to electron carriers, rather than directly to O2

Autotrophs= are self-feeders that sustain themselves without eating anything derived from other organisms
