Match the following:
A. Proton motive force
B. Terminal electron acceptor
C. Reducing power
D. Anabolism
E. Substrate

1. Form of energy generated as an electron transport chain moves protons across a membrane to create a chemiosmotic gradient.
2. Reduced electron carriers such as NADH, NADPH, and FADH2; their bonds contain a form of usable energy.
3. Substance on which an enzyme acts to form products; surface on which an organism will grow.
4. Chemical that is ultimately reduced as a consequence of fermentation or respiration.
5. Cellular processes that synthesize and assemble the subunits of macromolecules, using the energy of ATP; biosynthesis.
