Enzymes

Front

What is the site called where substrates are brought together in an enzyme-catalyzed reaction?

Back

Active site.

Front

What is any substance that is acted upon by an enzyme called?

Back

Substrate.

Front

What is the optimal temperature for enzyme activity based on a typical graph?

Back

30°C.

Front

What is the term for the complex formed when an enzyme binds to its substrate?

Back

Enzyme-substrate complex.

Front

What is the role of enzymes in biochemical reactions?

Back

To speed up reactions by lowering the activation energy.

Front

What are coenzymes?

Back

Organic molecules that assist enzymes in catalyzing reactions.

Front

What is the effect of temperature on enzyme activity?

Back

Enzyme activity typically increases with temperature up to an optimal point, after which it decreases.

Front

What happens to enzymes at very high temperatures?

Back

They can denature, losing their functional shape.

Front

What is the term for the molecules produced at the end of an enzyme-catalyzed reaction?

Back

Products.

Front

What is meant by enzyme specificity?

Back

Enzymes are specific to particular substrates due to their unique active sites.
