AP Biology- Enzymes and Energy

Front

What is competitive inhibition?

Back

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

Front

What is the active site of an enzyme?

Back

The specific region of an enzyme where the substrate binds and the reaction occurs.

Front

What type of macromolecule are enzymes?

Back

Enzymes are proteins that act as biological catalysts.

Front

Which enzyme breaks down starch into sugars?

Back

Amylase is the enzyme that catalyzes the breakdown of starch into sugars.

Front

What is an exergonic reaction?

Back

A chemical reaction that releases energy, often in the form of heat.

Front

What is an endergonic reaction?

Back

A chemical reaction that requires an input of energy to proceed.

Front

What role do enzymes play in biological reactions?

Back

Enzymes speed up chemical reactions by lowering the activation energy required.

Front

What is activation energy?

Back

The minimum amount of energy required for a chemical reaction to occur.

Front

What is allosteric inhibition?

Back

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

Front

What is a substrate?

Back

The reactant molecule that an enzyme acts upon.
