Enzymes

Front

What is enzyme inhibition?

Back

Enzyme inhibition is a process in which the activity of an enzyme is decreased, often due to the presence of a substance that binds to the enzyme.

Front

What is meant by the term 'specific' in relation to enzymes?

Back

Specific refers to the fact that each enzyme only has one substrate that fits its active site.

Front

What is the optimum pH for an enzyme?

Back

The optimum pH is the pH at which an enzyme's activity is at its maximum, which can vary for different enzymes.

Front

What factors can affect an enzyme's reaction rate?

Back

Factors that can affect an enzyme's reaction rate include temperature, pH, substrate concentration, and enzyme concentration.

Front

What is the active site of an enzyme?

Back

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

Front

How does temperature affect enzyme activity?

Back

Temperature can increase enzyme activity up to a certain point, after which high temperatures can denature the enzyme, reducing its activity.

Front

What is the role of substrates in enzyme reactions?

Back

Substrates are the reactants that enzymes act upon to facilitate a chemical reaction.

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.

Front

What is a non-competitive inhibitor?

Back

A non-competitive inhibitor is a substance that binds to an enzyme at a site other than the active site, reducing the enzyme's activity regardless of substrate concentration.

Front

What is enzyme specificity?

Back

Enzyme specificity refers to the ability of an enzyme to select and catalyze a specific substrate or group of substrates.
