Analogy for Competitive and Non- Competitive Enzyme Inhibition Rate Graph
Situation: Preschool birthday party game 'musical chair's'. The preschoolers are the substrate, the chairs are the enzymes.
Some of the parent's want to play. But the more preschoolers there are the less likely the dads are going to get a seat when the music stops. Eventually there will be a point when they are out competed for the seats because there are so many preschoolers
Non Competitive Inhibition
The preschoolers have older siblings who are too cool to be at a party like this. When the music starts they run around pushing the chairs over so they can't be used in the game anymore. It doesn't matter how many preschoolers there are they can't ever fill all of the chairs because some are out of action.
