i had a question that said in glucose degradation oxygen is the final acceptor of electrons............but isn't that in the ETC part which is separate from glycolysis? what do you guys think?

What is really "seperate"?....it's really all inter-dependent.

yes ETC is separate from glycolysis. ETC: mitoch., glycolysis:cytoplasm

so the statement that "in glucose degradation oxygen is the final acceptor of electrons" is wrong right?

You could consider glucose degradation as including the processes of glycolysis, krebs and ETC. Since oxygen is the final acceptor of electrons in the final step, it would be a correct statement.

question is a bit vague. Not sure what they mean by that, but I guess during ETC no part of glucose is degraded. Does that mean only glycolysis and krebs cycle ?! Not sure...

lets just hope this question doesn't show up on the DAT 😉

I really think that by glucose degradation, they are referring to the whole process of respiration. That would make the statement true.

Speaking of bio, just took my final this morning. Glad to be done with my summer classes! 🙂


*edit* From my textbook:

"The story of the breakdown of glucose - the saga of one molecule's transformation - is nearly complete. The only unfinished business lies at the end of the ETC. As noted earlier, oxygen is the final acceptor of the working electrons."

I guess it is a little vague to call respiration "glucose degradation", but I think the general idea can be deduced.

Usually glucose degredation refers to TOTAL degredation (removal of all energy stored in chemical bonds) in order to yield a final oxidized product (oxygen in this case).
