Enzyme never changes

Enzyme is recycled after use

Multiple Choice

What occurs to an enzyme after it breaks down a substrate?

• It attaches to another substrate.

• It is broken down and becomes unusable

• It is slightly altered and binds to a different substrate.

• It changes shape and uses ATP to bind to another substrate.

They LOWER ACTIVATION ENERGY

​How enzymes speed up reactions

Multiple Choice

How do enzymes affect biological reactions?

• Enzymes increase the activation energy required for a reaction, increasing the reaction rate.

• Enzymes decrease the activation energy required for a reaction, decreasing the reaction rate.

• Enzymes decrease the activation energy required for a reaction, increasing the reaction rate.

• Enzymes increase the activation energy required for a reaction, decreasing the reaction rate.
