Title: VCAA '06 Q4b
Post by: humanimal on June 08, 2011, 01:52:49 pm
"Where in the mitochondria does electron transport and ATP production occur?"

I answered,
Electron transport occurs on the cristae of the inner mitochondiral membrane and ATP production occurs in the matrix of the mitochondria and on the inner mitochondrial membrane.

Is this correct? The assesment report makes no mention of the matrix of the mitochondria (where ATP are produced in the Krebs cycle); as if they were only only specifying ATP production of the electron transport chain.

Is this a case of giving too much information and being incorrect?

You're correct in saying that ATP is produced from the Krebs cycle in the matrix.
in my opinion you would still get this correct, however, just a note that the bulk of ATP production occurs during the electron transport chain (34molecules, Krebs produces 2 ATP)
I would just add in, the Krebs cycle occurs in the matrix, producing ATP as well

depends how u were taught, sometimes they teach 36ATP or 38ATP, doesn't really matter.

All you have to say is cristae.
