Induced Fit. When an enzyme binds to the appropriate substrate, subtle changes in the active site occur. This alteration of the active site is known as an induced fit. Induced fit enhances catalysis, as the enzyme converts substrate to product.
1.) It's best to have two pair of eyes for an experiment. Meaning one person to watch the chemicals while you're writing things down - especially if they're dangerous if mixed together. Basically it's best to take turns!
2.) They may have different results than you if you're in a lab - and it's always best to work together to get the job done! You can get the job done faster and more effectively if you work together! (:
