AP Biology Enzymes

Front

What is Competitive Inhibition?

Back

A type of enzyme inhibition where a molecule similar to the substrate competes for the active site of the enzyme.

Front

What type of macromolecule are enzymes?

Back

Enzymes are proteins.

Front

How can the rate of an enzymatic reaction be increased?

Back

By adding more enzyme.

Front

What is the enzyme-substrate complex?

Back

The intermediate formed when an enzyme binds to its substrate.

Front

How do temperature changes affect enzyme activity?

Back

Enzymes function best at their optimal temperature; lower temperatures reduce reaction rates.

Front

What is Allosteric Inhibition?

Back

A form of enzyme regulation where an inhibitor binds to a site other than the active site, changing the enzyme's shape and function.

Front

What is Noncompetitive Inhibition?

Back

A type of inhibition where an inhibitor binds to an enzyme regardless of whether the substrate is bound, reducing the enzyme's activity.

Front

What is Feedback Inhibition?

Back

A regulatory mechanism where the end product of a metabolic pathway inhibits an enzyme involved in its synthesis.

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 specific region of an enzyme where the substrate binds.
