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 substrate in the context of enzymes?

Back

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

Front

What does it mean for an enzyme to be denatured?

Back

Denaturation is the process in which an enzyme loses its functional shape due to high temperature or extreme pH, rendering it inactive.

Front

What is the optimum pH for an enzyme?

Back

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

Front

What is the optimum temperature for enzyme activity?

Back

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

Front

How does temperature affect enzyme activity?

Back

As temperature increases, enzyme activity typically increases until it reaches the optimum temperature, after which activity declines due to denaturation.

Front

What happens to enzyme activity at extreme pH levels?

Back

Extreme pH levels can lead to denaturation of the enzyme, resulting in decreased activity.

Front

What is the relationship between enzyme concentration and reaction rate?

Back

Increasing enzyme concentration generally increases the reaction rate, provided there is enough substrate available.

Front

What is the role of coenzymes in enzyme activity?

Back

Coenzymes are organic molecules that assist enzymes in catalyzing reactions, often by acting as carriers for chemical groups.
