Regulation of Enzyme Concentrations Quiz

Regulating enzyme concentration involves managing the turnover number, which is the balance of synthesis and degradation.

• True

• False

Enzyme concentration can be increased only through the degradation process.

• True

• False

Induction of enzyme synthesis can be initiated by hormones and growth factors.

• True

• False

The half-life of enzymes can vary significantly, affecting how long they remain active within the cell.

• True

• False

Proteolytic enzymes (proteases) are responsible for the degradation of enzymes in both lysosomes and proteasomes.

• True

• False

The ubiquitin pathway plays a crucial role in regulating enzyme degradation within proteasomes.

• True

• False

Control mechanisms for enzyme activity include both controlling enzyme availability and substrate availability.

• True

• False

Control of enzyme availability involves regulating gene expression for enzymes.

• True

• False

Constitutive enzymes are produced in response to specific environmental conditions.

• True

• False

Inducible enzymes are required only under special conditions, such as the presence of specific substrates.

• True

• False
