Enzyme

Front

What is the enzyme-substrate complex?

Back

The intermediate formed when an enzyme binds to its substrate.

Front

What is the optimum pH for enzyme activity?

Back

The pH at which an enzyme is most active, often around 6.6 for many enzymes.

Front

What role do enzymes play in biochemical reactions?

Back

They lower the activation energy required for reactions to occur.

Front

What factors can affect enzyme activity?

Back

Temperature, pH, substrate concentration, and enzyme concentration.

Front

What is the active site of an enzyme?

Back

The region on the enzyme where the substrate binds.

Front

How does temperature affect enzyme activity?

Back

Increased temperature generally increases activity up to a point, after which the enzyme may denature.

Front

What happens to an enzyme after it catalyzes a reaction?

Back

It remains unchanged and can catalyze subsequent reactions.
