(b)+Enzyme+models

1. Draw the lock & key model of enzyme activity. Write a few sentences to explain this. 2. Write 4~5 really good sentences to decribe this process
 * Substrates bind to the active site (combines with the substrate) causes the changes in the distribution of electrons in the chemical bonds of the substrate and ultimately causes the reactions that lead to the formation of products. The products are releasred from the enzyme surface to regenerate the enzyme for the another reaction cycle. The active site has a unique geometric shape that is complmentary to the geometric shape of a substrate molecule, similar to the fit of puzzle pieces. This means that enzymes specifically react with only one or a very few similar compounds to have a reaction.

3. How does the induced fit model of enzyme activity differ from the lock & key model? (You need to think for yourself for this one)
 * Unlike the Lock & key model, the fit induced model does not separate the products after the reaction
