NOB 2 QS HELP ;)

[_inspire45]

Hey guyss!

So, I have been studying Nature of Biology 2 chapter 2 and took quite good notes on the content. However, I began the chapter review questions and felt that some questions were not explained in the content. 

Example, "The folded internal membranes of the mitochondria have many stalked particles on their innermost surfaces. Given the function of mitochondria and where most of the reactions occur, of what advantage might the presence of these particles be for the production of ATP in the organelle"

Though I can guess the answer, I'm still not sure why they hadn't explained about stalked particles in the chapter nor had they explained it in NOB 1. How should I approach such questions?Should I research the answer on the net or use a different Biology book to aid me in such situations? 

Please help guys   All answers are appreciated!!
Thanks:)

This is really an example of an application question; underlying concepts disguised under unfamiliar contexts.
Just remember that every question must relate to something that you have learnt, even if it isn't obvious.

Model Answer:

The 'stalked particles' would provide a greater surface area of the internal membrane of the mitochondria. This would provide a greater area in which the reactions of cellular respiration can occur, hence increasing the rate of said reactions.

Questions that focus on high folding often require you to identify that you're increasing surface area, and then follow this up by how beneficial it is. So, the highly folded inner membrane increases the surface area within the mitochondria. Given that the electron transport chain (a reaction in aerobic respiration) takes place within the cristae (highly folded inner membrane, increasing SA increases the rate of this process, increasing the provision rate of ATP for the cell.
