Hi there

NAD coenzyme. Although I don't think you have to remember this.

she also asked me why oxygen is referred to as the “terminal oxygen acceptor” in respiration and i was even more lost. do you have any ideas?

do you mean electron acceptor? its because in the electron transport chain, it accepts the electrons and protons, forming a water molecule so there aren't just low energy electrons lingering in the mitochondria- its terminal because this is the last thing that happens to the electrons during respiration

Hi again.

I believe that the term she wanted simply describes the role of the enzyme. As I said knowing the enzymes name isn't essential I imagine, this is perhaps why she wanted this response and why google is telling you the actual name.

I wouldn't worry too much so long as you understand the process of respiration. If you do need to remember it but don't I think you'd only really drop 1 mark.

Hope this makes sense.

oxygen as the final electron acceptor is the final step in oxidative phosphorylation (so after the Krebs Cycle - the reduced NAD comes from the Krebs Cycle (or glycolysis or the link reaction) and goes into OP)
