What does it mean to say that enzymes are specific?

Enzymes are specific since they always act on a certain substrate. The substrates that are obviously specific bind to the active site of the enzyme where they are chemically modified to become one or more products. The reaction is generally reversible.

Explanation:

the potatoes have high sugar concentrations and although these potatoes were different we could seethe effects that their sugar concentrations had in different environments. for example, the potatoes in sample a, were placed in pure water. this created a hypertonic environment and caused the potatoes to draw in water from its surroundings. we saw the opposite happen with the potatoes in sample b when placed in the sodium chloride solution. the potatoes in this case were in a hypotonic solution and therefore lost water to their surroundings.
