Question
Chapter 20, Problem 12RE
Interpretation Introduction
Interpretation:
The electron donor and acceptor species, and the overall voltage of the given biological reaction are to be determined.
Concept introduction:
Oxidation is the addition of an electronegative element or the removal of an electropositive element in a
Reduction is the addition of an electropositive element or the removal of an electronegative element in a chemical reaction.
The chemical reaction in which oxidation process and reduction process takes place and reduction take place simultaneously is called a
Cytochromes are the types of proteins that consist of iron as the heme group.
