enzymes bring down the "wall" so what advantage do you suppose there is... For an enzyme to participate in this kind of chemical reaction? i guess it's like... an enzyme lowers the wall to make the climb easier. Going dow n! enzyme to the rescue! on a basic level, that's exactly right! For example, let's imagine you're a substrate, Kumi. To reach your destination and transform into a reaction product, you need to leap over an intimidating six-foot wall, But that's just too high! Then along comes Mr. enzyme, who smashes the wall down to size. Now the six-foot No pro blemo! That enzyme is such a sweetheart!
