Our teacher hinted at an essay question regaurding the various ways ATP is made. I am having a hard time differentiating between Subrate level phosporylation and oxidative phosphorylation. Can someone put it into laymans (sp?) terms so that this stuff I'm getting from google searches and the book will make sense?? Any explaination will help though. Thanks in advance!

• Energy released during certain metabolic reactions can be trapped to form ATP from ADP and VP (phosphate). Addition of a VP to a molecule is called phosphorylation.
• During substrate-level phosphorylation, a high-energy VP (phosphate) from an intermediate in catabolism is added to ADP to produce ATP.
• During oxidative phosphorylation, energy released as electrons are passed to a series of electron acceptors (an electron transport chain) and finally to O2 or another inorganic compound.

Hope this helps

Thanks.. We had our test on this last Thursday and we did, in fact, have a question asking for the various ways ATP is made. I don't think I mentioned anything about the electron transport chain in the explaination of oxidative phosphorylation, so I'm a little worried about that because she did stress that in lecture.. Otherwise I think I probably pulled a b on the test. We'll see.. Thanks so much for helping me
