A competitive inhibitor

• binds to the allosteric site, blocking the substrate

• binds to the active site, blocking the substrate

• has a different shape than the enzyme

• lowers the activation energy of a reaction

An example of a non-competitive inhibitor is

• mercury

• oxaloacetate

• lactase

• glucose

During the production of the essential amino acid isoleucine, _____________________ acts as the ___________________ inhibitor of threonine.

• Isoleucine, non-competitive

• Threonine deaminase, non-competitive

• Isoleucine, competitive

• Threonine deaminase, competitive

Enzymes are useful for chemical reactions because they ________________________________________.

• increase the activation energy

• lower the activation energy

• decrease the rate of reaction

• increase inhibition

An inhibitor is a molecule that binds to the enzyme

• and speeds up the enzymes function

• is always reversible

• slows down or stops the enzymes function

• is always irreversible

Chemogenetics involves

• bioinformatics and metabolic pathways

• chemicals and genes

• biochemistry and DNA

• competitive and non-competitive inhibition

What colour line represents non-competitive inhibition?

• Green

• Orange

• Blue
