NADH passes electrons into the electron transport chain. List the carriers that would receive the electrons, in the correct order.
What is the difference between homolactic and heterolactic fermentation routes?
Name any chemical compound that can be used as an initial electron donor by the chemolithotrophs.
Homework Answers
ANSWER :
The correct order of carriers that would receive electrons, passed from NADH during electron transport chain (ETC) :-
Coenzyme Q (ubiquinone) 
Cytochrome
bc1 complex Cytochrome
c (Cyt c) Cytochrome
c oxidase molecular
oxygen (final electron acceptor).
In homolactic fermentation, the pyruvate reduced via pyruvate dehydrogenase enzyme and produces lactic acid or lactate as end product while heterolactic fermentation occurs during phosphoketolase pathway, which produces CO2 and ethanol (C2H5OH) in addition to lactic acid.
Chemolithotrophs use various inorganic chemical compounds as initial electron donor e.g.- sulfide (H2S), ferrous iron (Fe++) etc.

What are the names of the four complexes in the electron transport chain? What molecules/electron carriers donate electrons to the complexes? What molecules carry the electrons between the complexes (e.g. from complex II to III)? The following are electrons carriers in the complexes: cytochromes a, a3, b, and c1, FAD, FMN. Assign them to the right complexes.

Overall electron flow in a cell using reverse electron transport Consider a cell that is using reverse electron transport to generate NADH and is not (for the moment) using the proton gradient for anything else. Assume the cell is not a phototroph (so electrons are not being recycled by light-driven pumping). Also assume that the proton gradient is produced solely by a Q-cycle like the one we've discussed, which pumps 2 protons per electron transferred. (This would imply that the...
