Welcome to the Apple Support Communities
You have a Mid/Late 2007 MacBook Pro, so you can purchase and run OS X Mountain Lion without any problem.
Also, open > About this Mac, and check Memory. I recommend you to install at least 4 GB of memory to run OS X Mountain Lion. You can buy it in OWC or Crucial > http://eshop.macsales.com/shop/memory/MacBook/Pro/Core2/
Opps, a few stupid typos and Doh! I forgot the Profiler info. I'm such a dweeb sometimes. Pardon...

Also, I forgot to tell you that you have to upgrade to Snow Leopard first before purchasing Mountain Lion > http://store.apple.com/us/product/MC573/mac-os-x-106-snow-leopard
Before upgrading, make a backup of your data. Then, insert the DVD and upgrade. After upgrading, open > Software Update to install the most recent Snow Leopard version, so App Store will appear on the Dock. Open it and purchase OS X Mountain Lion. Check if your applications are supported > http://www.roaringapps.com
And BTW, this was the first time I ever used the Apple Support Communities to help since my first Mac purchase in 1987 - a black and a white 9" that I eventually Upgraded to an SE for $900 more and paid $400 extra for a Rodine 20MEGAbyte HD! And I've purchased new machines every 2 to 4 years along the path! This is only in a small way a testimony to my own DIY fortitude and more of one to the quality of Apple hardware which has given me very little trouble to speak of. Some of these Macs are still in use as I've handed them down to my wife and kids - my commercial photography biz requiring always newer gear. As a side biz I've done done my entire adult life I play saxophone and keys as a single and in different duos and trios with longtime musician buddies. I say this because the MacSE I mentioned above is still in use as a MIDI file player (with a little bigger HD) and works flawlessly and without fail at it's singular task on many weekends. And the only trouble it has ever given me was a power supply failure many years ago, for which I had to pay $250 to replace. That power supple failed several years later also, however at that point I had fortunately had the foresight to scoop up four other SE's that sit in my closet awaiting cannibalization. The cost? One dollar each at a University garage sale! Woot. As they say, one man's garbage... and thanks again, I'll be back!
