Chapter 26, Problem 6TYU
Summary Introduction
To review:
The use of the term “energy source” instead of “electron donor” by the biologists.
Introduction:
The electron donors are the chemical species, which are able to donate electrons to the other compounds. The biologists prefer to use the term “energy source” for these electron donor species.
