I took two full years at a CC. Had a C+ in intro bio and other "unmentionables". Do they care?
The short answer is, kindof., but not in a major way.
It didn't stop me from being offered interviews at Columbia, Jefferson, OHSU, Einstein, UVM, GWU, Albany, Drexel, and NYMC. No rejections; the acceptances are now rolling in.
I did, however, have to show that I wasn't going to a CC for easy "A"s. I think it helped that my upper division work was outstanding and my MCATs were reasonable. I've also got a resume that reads like one of those movies about new deal heroes, who saved the world in WWII, eradicated smallpox, and created the American dream. I needed an excuse to have gone to CC, though. For me, it was that I worked full time to support my widowed mother and her 6 kids. After explaining that, they left me alone.
Just do your best, do what you love, work hard, and you'll be a damned good doctor in a few years.
