Answer:
competitive
Explanation:
An inhibitor is a substance that hinders the action of an enzyme. An inhibitor may be competitive or non competitive.
A competitive inhibitor is an inhibitor that is very similar to the substrate hence it binds to the enzyme instead of the substrate. A noncompetitive inhibitor binds to a site that is different from the active site. This site is called an allosteric site.
If we look at the experiment described in the question, the reaction rate decreases upon addition of the inhibitor. This effect is reversed by adding a large quantity of substrate.
The implication of this observation is that the enzyme and the inhibitor compete for the active site on the substrate.
Hence the inhibitor is a competitive inhibitor.

Looking at the images and the boxes, it goes like this;
To add external functionality of external backup, you would probably have something removable from the computer accessable. This means that the Optical Drive would add functionality of external backup, and the first tile goes there.
A processor is what does the general computations inside a laptop/desktop computer and processes information as the name implies. Upgrading the processor makes it go faster. The second tile would go to the processor.
The third one need no further explanation and would go to the Hard Drive, but just keep in mind that the Hard Drive stores all the information on your computer (i.e. Applications, Photos, etc.).
Hope this helps!
