How do enzymes speed up chemical reactions?

When a piece of liver is dropped into hydrogen peroxide, bubbles are released from the liver as the hydrogen peroxide (H2O2) decomposes into water (H2O) and oxygen (O2). This rapid change in reaction rate suggests

Cells must produce many different enzymes because

When a piece of liver is dropped into hydrogen peroxide, bubbles are released as the hydrogen peroxide (H2O2) decomposes into water (H2O) and oxygen (O2). However, if the liver is cooked first, the reaction fails to occur. The reason for this is
