Question #145: Bacteria derive their energy from:
A) Krebs cycle
B) Glycolysis
C) Electron Transport Chain
D) A and B
E) B and C

Solution Answer: (D) Prokaryotes such as bacteria do not have a mitochondria and do not carry out the TCA cycle, however they do carry out glycolysis and have their own electron transport system.

So I came across this question again today during my second attempt at the Destroyer biology section, but it caught my attention this time. My first time around, I wasn't aware that bacteria have an ETC, so that was news to me. But based on the answer solution given, shouldn't the real answer be E? It says that bacteria carry out glycolysis and have an ETC, but lack mitochondria. In order to even perform the Kreb's (TCA) cycle, mitochondria would be needed which clearly bacteria do not have.

Any thoughts or comments would be greatly appreciated! I realize this is a bit of nit-picking at the Destroyer biology section, but I'm trying to understand why every answer choice for each question is correct/wrong.

It's a typo. Bacteria run both glycolysis and electron transport chain. In fact, bacteria have multiple ETCs.

He seems to have corrected it in the 2011 version. Now, its answer is E, and it reads "Prokaryotes such as bacteria do not have a mitochondria and do not carry out the TCA cycle, however they do carry out glycolysis & have their own electron transport chain."

Thanks for the quick responses, that cleared things up. And I have the 2011 version too..weird that it's still a typo in my version.

They recycled ---> changed the covers on the extra 2010 versions lying around.

Evidently they did more than that if mine has the corrected answer, E?

Key word in my post is "extra". (Btw, it was meant as a joke. smh)

After these long days of studying, I've noticed my jokes becoming quite stale as well. Sad story.

It's okay. Stale jokes or puns would be seeing the words "oxiDATion" and "******ATion" on everywhere you go. Oh wait, it's been done.
