Front

What is the function of the rough endoplasmic reticulum (ER)?

Back

The rough ER synthesizes proteins and transports them to the Golgi apparatus for modification.

Front

What role does the extracellular matrix play in tissue structure?

Back

The extracellular matrix provides structural support and regulates cell behavior; degradation can lead to tissue damage.

Front

What is the significance of the cytosol in cellular metabolism?

Back

The cytosol is the site of metabolic reactions; changes can affect enzyme activity and metabolic pathways.

Front

How does substrate concentration affect enzyme kinetics?

Back

Enzyme activity increases with substrate concentration until the enzyme becomes saturated.

Front

What is the active site of an enzyme?

Back

It is where the substrates bind and react.

Front

What is the function of the smooth endoplasmic reticulum (ER)?

Back

The smooth ER is involved in lipid synthesis and detoxification processes.

Front

What is the role of enzymes in biochemical reactions?

Back

Enzymes act as catalysts to speed up chemical reactions without being consumed in the process.

Front

What is enzyme saturation?

Back

Enzyme saturation occurs when all active sites of the enzyme molecules are occupied by substrate, leading to maximum reaction rate.

Front

What is competitive inhibition in enzyme activity?

Back

Competitive inhibition occurs when a substance competes with the substrate for binding to the active site of the enzyme.

Front

What is the importance of pH in enzyme activity?

Back

Enzymes have optimal pH ranges; deviations can lead to decreased activity or denaturation.
