Which graph has a lower energy of activation?

Back

Graph B

Front

How do enzymes speed up chemical reactions?

Back

Lower the energy of activation

Front

The image highlights the location on the enzyme where the substrate binds to the enzyme. The enzyme changes shape and then perform the reaction. What is this location called where the reaction occurs?

Back

Active Site

Front

True or False: If you change the shape of the enzyme so that the substrate cannot bind to it, the reaction cannot occur.

Back

True
