Thousands of simultaneous chemical reactions occur in the body that involve transfer of electrons from one substance to another. These reactions are either oxidation or reduction. Explain both.#2 The story of how the body maintains its continuous energy supply begins with Adenosine Triphosphate (ATP). Discuss how energy is trapped in ATP, how ATP is broken down, and how it immediately reforms itself.

Compare and contrast these and discuss how each is measured.#6 The respiratory quotient (RQ) feres to the ratio of metabolic gas exchange.
