Document Summary

It is used to reduce nad+ to nadh: exhaled as part of co2, becomes part of newly formed h20, a and b, b and c. Pyruvate to co2 oxygen is not directly involved in that process: a is not true. It takes the electrons and it does get converted to water. Oxygen is a not very good reducing agent: oxidizing agent, oxygen will oxidize, remove electrons, nad+ to nadh is adding electrons opposite of what oxygen does, oxygen oxidizes nadh to nad+ Because it is a redox process, it is called oxidative phosphorylation: oxidizing the carbons. Coenzyme = organic cofactor, often a reaction substrate: subclass of cofactor, ex. Organic, based on carbon: enzymes are catalysts and do not change in the course of the chemical reaction, but a. Coenzyme could be a substrate will be changed during the course. Just because it has the word enzyme in it does not mean that it is unchanged during the reaction.
