Chapter 18, Problem 15E
Summary Introduction

To explain: The reason why it is possible for electrons to flow from a redox center with a more positive ε°' to one with a more negative ε°' within an electron-transfer complex.

Concept introduction: The redox potential, ε is the measure of the tendency of molecules to get reduced by accepting electrons from electron donors. The electron transport chain involves a lot of electron donors and electron acceptors.

Macmillan Learning Cholesterol synthesis begins with the formation of mevalonate from acetyl CoA. This process activates mevalonate and converts it to isopentenyl pyrophosphate. Identify the atoms in mevalonate and isopentenyl pyrophosphate that will be labeled from acetyl CoA labeled with 14C in the carbonyl carbon. Place 14C atoms and C atoms to denote which carbon atoms are labeled and which are not labeled.
