11.A Enzymes R.A.R.E Day

Enzymes increase the activation energy required.

Enzymes decrease the activation energy required.

Enzymes have no effect on activation energy.

Enzymes stop the reaction from occurring.

Product

Active site

Substrate

Enzyme

It produces the product

It binds to the substrate

It is the enzyme itself

It changes the substrate

It becomes the active site

It is converted into the product

It remains unchanged

It becomes the enzyme

The products are released

The enzyme breaks or bonds the substrate

The substrate binds to the enzyme

The enzyme is reused

Enzyme-product complex

Enzyme-substrate complex

Product

pH can speed up the enzyme.

pH can denature the enzyme.

pH has no effect on the enzyme.

pH can slow down the enzyme.

They work best

They are slow

They denature and no longer work

They increase in rate

Enzyme activity increases indefinitely with temperature.

Enzyme activity decreases as temperature increases.

Enzyme activity increases with temperature up to a certain point, then decreases.

Temperature has no effect on enzyme activity.
