3.1 - 3.3 Enzymes

Front

What are enzymes?

Back

Enzymes are biological catalysts that speed up chemical reactions in living organisms without being consumed in the process.

Front

What is the role of substrates in enzyme activity?

Back

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

Front

What is meant by enzyme saturation?

Back

Enzyme saturation occurs when all active sites of the enzyme molecules are occupied by substrates, and the reaction rate reaches its maximum.

Front

What is feedback inhibition?

Back

Feedback inhibition is a regulatory mechanism in which the accumulation of an end product slows down or stops the process of its own production.

Front

Which biomolecule group do most enzymes belong to?

Back

Most enzymes belong to the group of proteins.

Front

What is the optimal temperature for enzyme activity?

Back

The optimal temperature is the temperature at which an enzyme functions most efficiently.

Front

What is the optimal pH for enzyme activity?

Back

The optimal pH is the pH level at which an enzyme's activity is at its highest.

Front

What are products in the context of enzyme reactions?

Back

Products are the substances that are formed as a result of the enzyme-catalyzed reaction.

Front

What is activation energy?

Back

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

Front

What is competitive inhibition?

Back

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