Enzymes Review

Front

What is the primary role of enzymes in biological systems?

Back

Enzymes act as catalysts to speed up chemical reactions.

Front

What are enzymes primarily composed of?

Back

Enzymes are primarily composed of amino acids.

Front

How do enzymes affect the activation energy of a reaction?

Back

Enzymes lower the activation energy required for a reaction to occur.

Front

What does the principle of conservation of matter state?

Back

Matter can neither be created nor destroyed.

Front

What type of macromolecule are enzymes classified as?

Back

Enzymes are classified as proteins.

Front

What is a catalyst?

Back

A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process.

Front

What is the significance of the active site in an enzyme?

Back

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

Front

What factors can affect enzyme activity?

Back

Factors that can affect enzyme activity include temperature, pH, and substrate concentration.

Front

What is the difference between competitive and non-competitive inhibition?

Back

Competitive inhibition occurs when an inhibitor competes with the substrate for the active site, while non-competitive inhibition occurs when an inhibitor binds to a different part of the enzyme, altering its function.

Front

What is enzyme specificity?

Back

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