Several years ago I spent one October afternoon seeking out a pool supply shop to grab 4 pool noodles.  Could I have gotten them cheaper at the end of the summer? Yes.  Could I have avoided that ugly brown at the end of the summer?  Yes.  Was I thinking about enzyme models at the end of the summer? No.

I saw this at a mini CAST I went to the first year I was teaching.  Anything else I was slacking at?  Of course!  I didn't do the best job creating these models.  I used a old steak knife in the back of my lab to saw my pool noodles into circles.

The green piece is the enzyme. with an active site and allosteric site.

The blue and brown pieces are supposed to be the same size - one is the substrate one is the competitive inhibitor.

The orange piece is supposed to be smaller and be a non competitive inhibitor.

We also discuss how now models are perfect and what we can show versus what we cannot show with this model.
