24. ENZYMES!!
A type of PROTEIN
They speed up chemical reactions

25. Enzymes are Specific
A specific enzyme will fit it’s specific substrate
Lock and key fit
Enzymes are used over and over

26. Enzyme Substrate Activity Instructions
Get the following:
1 Piece of construction paper
1 blue hand out
1 pink handout
Scissors and glue
Cut out substrates first!
Then cut out the enzymes and make the substrate enzyme complex.
Then cut the products, and glue them beside the complex.
After you have cut out and pasted all complexes answer the 5 questions on the back of your notes from today on Enzymes
