Address the following regarding Oxidative Phosphorylation?
1. Why are the processes of the ETC and ATP Synthase always coupled? What is the “oxidative” part refer to? What is the “phosphorylation” refer to?
2. What type of transport is the ETC an example of? Explain why.
3. Discuss how Ox-Phos is similar to the active transport of glucose.
4. Define/Discuss the relationship between proton motive force, electrochemical gradient before/after ETC, ATP synthase and chemiosmosis (via ATP synthase).
