Chemistry V: Oxidation and Reduction
Topic 10: Oxidation and reduction in metabolism
Now watch this short lecture that Introduces Oxidation and Reduction provided by the Khan Academy.
The redox reaction is an important type of reaction in human physiology. View this “crash course in redox.” It provides a very quick, brief description of the relevance of redox reactions to our lives. The lecture moves very quickly, so follow up by viewing this Bozeman Science video. After you have viewed these linked lectures, answer the following questions:
What examples of redox reactions are given in the videos?
What component of the atom is exchanged in this type of reaction?
Which type of bonding is involved in redox reactions?
What is the oxidation number? Why is oxygen always -2 and hydrogen always +1?
What reaction has “saved more lives in the history of chemistry”? Explain it.
What applications were described at the end of the Bozeman Science video on redox reactions? How do they apply to living organisms and what can you calculate or determine from them?
