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 optimal temperature for enzyme activity?

Back

The optimal temperature is the temperature at which an enzyme's activity is highest, often around 30°C for many enzymes.

Front

What is activation energy?

Back

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

Front

How do enzymes affect activation energy?

Back

Enzymes lower the activation energy required for a reaction, making it easier for the reaction to occur.

Front

What is a substrate?

Back

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

Front

What is an active site?

Back

The active site is the specific region of an enzyme where the substrate binds and the reaction occurs.

Front

What is an enzyme-substrate complex?

Back

An enzyme-substrate complex is the temporary complex formed when an enzyme binds to its substrate.

Front

What is a catalyst?

Back

A catalyst is a substance that increases the rate of a chemical reaction without undergoing any permanent chemical change.

Front

What happens to enzymes at high temperatures?

Back

At high temperatures, enzymes can denature, losing their shape and functionality.

Front

What is the role of enzymes in metabolic pathways?

Back

Enzymes facilitate and regulate metabolic pathways by speeding up the chemical reactions involved.
