Android doesn't work like that, in a manner of speaking.
In popular launchers (including the 'stock' one) there's the "app drawer", accessible from all home screens. It's an alphabetical listing of all installed apps; it is ~5 icons wide and scrolls vertically.
Icons (shortcuts) or widgets added to home screens are merely user-created convenience shortcuts to get to apps.
This is analogous to desktop shortcuts vs navigating the start menu on Windows.

As I said to commandar, I don't really understand the argument in that case. If you don't actually use the left/right screens to store apps, then saying that it's a more efficient way to access apps is meaningless. On the iPhone, where screens 1-N are typically filled with apps, the left/right scrolling would be very unfriendly.
You can assign each home screen a task, and put apps for that task in each screen. You might usually use these apps together, so it gives a bit of a logical ordering. Then you can find apps you don't usually use in the list of every app.
