A specific enzyme will fit it’s specific substrateLock and key fit
Enzymes are used over and over
Enzyme Substrate Activity Instructions
1. Get the following:a. 1 Piece of construction paperb. 1 blue hand outc. 1 pink handoutd. Scissors and glue
2. Cut out substrates first!3. Then cut out the enzymes and make the
substrate enzyme complex.4. Then cut the products, and glue them beside
the complex.5. After you have cut out and pasted all
complexes answer the 5 questions on the back of your notes from today on Enzymes
