AP Biology - Energy & Enzymes

Front

What is an Allosteric Site?

Back

A receptor site on an enzyme where a molecule can bind, causing a change in the shape of the active site, which can enhance or inhibit enzyme activity.

Front

Where do substrates bind on an enzyme?

Back

Substrates bind at the active site of an enzyme.

Front

How do enzymes increase the rate of a chemical reaction?

Back

Enzymes increase the rate of a chemical reaction by reducing the activation energy required for the reaction to occur.

Front

What happens when the production of enzyme Trp-T decreases?

Back

A decrease in the production of enzyme Trp-T leads to a decrease in I3PA and IAA concentration.

Front

What is thermal energy?

Back

Thermal energy is the energy associated with the random motion of molecules, often perceived as heat.

Front

Define Activation Energy.

Back

Activation energy is the minimum energy required for a chemical reaction to occur.

Front

What is an enzyme?

Back

An enzyme is a biological catalyst that speeds up chemical reactions in living organisms by lowering the activation energy.

Front

What is the role of the active site in an enzyme?

Back

The active site is the specific region of an enzyme where substrates bind and undergo a chemical reaction.

Front

Explain the concept of enzyme specificity.

Back

Enzyme specificity refers to the ability of an enzyme to select and catalyze a specific substrate among many possible candidates.

Front

What is a competitive inhibitor?

Back

A competitive inhibitor is a substance that competes with the substrate for binding to the active site of an enzyme, thereby reducing enzyme activity.
