Enzyme Function and Characteristics

Front

What is a substrate?

Back

The substrate is the substance on which an enzyme acts.

Front

What is the role of an enzyme in a chemical reaction?

Back

An enzyme acts as a catalyst to speed up the reaction by lowering the energy of activation.

Front

What is the active site of an enzyme?

Back

The active site is the region of an enzyme that attaches to a substrate.

Front

How do enzymes affect the energy of activation?

Back

Enzymes lower the energy of activation required for a reaction to occur.

Front

What happens to enzymes during a reaction?

Back

Enzymes are not consumed during the reaction; they can be used repeatedly.

Front

What is the effect of pH on enzyme activity?

Back

Enzymes function best at specific pH levels; extreme pH values can denature enzymes.

Front

What is denaturation in the context of enzymes?

Back

Denaturation is a change in the shape of an enzyme that can result from changes in temperature or pH, affecting its function.

Front

What are products in a chemical reaction?

Back

Products are the substances that are produced as a result of a chemical reaction.

Front

What is the difference between competitive and non-competitive inhibitors?

Back

Competitive inhibitors bind to the active site of an enzyme, while non-competitive inhibitors bind to a different part of the enzyme.

Front

What is an enzyme's specificity?

Back

Enzymes are specific to their substrates, meaning each enzyme only catalyzes a specific reaction.
