Contradiction in CliffsAP Bio 3rd edition...

Members don't see this ad.

On page 48 it says substrate level phosphorylation occurs in the Krebs Cycle. Yet on the very next page (page 49) it says that substrate level phosphorylation occurs in glycolysis.
Which one is correct?
Also...is the DAT anal enough to ask a question on the specific numbers of ATP, NADH, and FADH2 being produced during respiration?

It occurs in both glycolysis and citric acid cycle. Substrate-level phosphorylation is a type of reaction that results in ATP formation via transfer of PO3 to ADP. It's not some specific step limited to just one pathway.

I haven't taken the DAT yet so I can't say, but it's probably good to at least know how many ATPs are produced.

alright,

So, SLP (sub level phos) uses the high energy bonds of PEP, 1,3 BPG from Glycolysis and Succinyl CoA from TCA cycle and by hydrolyzing them, makes ATP/GTP. No Oxygen in this one.

where ns oxidative phos, ETC (e transport chain) and proton pump gardient are responsible for this with the final electron acceptor, Oxygen. No more high energy molecules.

Hope this helps

I haven't come across this in the DAT, but I would know three things about metabolism: 1. Where each process occurs in the cell, and 2. How many ATPs are produced in each process, and 3. The name of major molecules

3rd edition more than millions+ sold... so that means there are slim to none mistakes...
