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 active site of an enzyme?

Back

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

Front

What is the optimum pH for enzyme activity?

Back

The optimum pH is the pH at which an enzyme's activity is at its maximum.

Front

How does temperature affect enzyme activity?

Back

Enzyme activity typically increases with temperature up to a certain point (optimal temperature), after which it decreases due to denaturation.

Front

What is denaturation in enzymes?

Back

Denaturation is the process where an enzyme loses its three-dimensional structure and, consequently, its functionality due to extreme conditions such as high temperature or pH.

Front

Why are enzymes considered reusable?

Back

Enzymes are not changed when they catalyze a chemical reaction, allowing them to be used repeatedly.

Front

What happens to enzymes at high temperatures?

Back

At high temperatures, enzymes can denature, meaning their shape changes and they can no longer function properly.

Front

What is a substrate?

Back

A substrate is the reactant molecule upon which an enzyme acts.

Front

What role do enzymes play in metabolic pathways?

Back

Enzymes facilitate and regulate the biochemical reactions that occur in metabolic pathways, allowing for efficient energy production and resource utilization.

Front

What is enzyme specificity?

Back

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