Just wondering in regards to the Kreb Cycle if we should say that the pyruvate molecule or acetyl coenzyme A is used as an input?
Thanks heaps!
You should be fine with using either. Technically the input is acetyl co-A but a lot of people won't be taught that because the details of krebs have been removed from the study design.
I've had a quick look through past examiners reports:
2016: Pyruvate is referred to as a substrate of the kreb's cycle
2010: "• Krebs (cycle): pyruvate is converted to carbon dioxide, 2 ATP produced "
2017: "The structure labelled Y is where: D. pyruvate is broken down, releasing carbon dioxide"
I only found one reference to acetyl coA and it was talking about details that are no longer on the study design. So I would just go with pyruvate but you should be fine to use either.
