1. Using what you know about the requirements for any chemical reaction to take place, briefly
explain the need for the energy investment phase in this catabolic reaction.
2. Where did these carrier molecules come from (what previous phase(s)?
3. When the electrons are released from these carrier molecules, what else is released?
4. Is the release of electrons from these electron carriers an oxidation or reduction reaction?
5. What is formed as a product of the electron transport chain? Did the formation of this molecule involve an oxidation or reduction reaction?
