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 functions most efficiently, often around 30°C for many enzymes.

Front

What are products in a chemical reaction?

Back

Products are the substances that are formed at the end of a chemical reaction.

Front

What is a substrate?

Back

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

Front

What is an enzyme-substrate complex?

Back

An enzyme-substrate complex is the temporary molecule formed when an enzyme comes into perfect contact with its substrate.

Front

What is the active site of an enzyme?

Back

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

Front

What happens to enzymes at high temperatures?

Back

At high temperatures, enzymes can denature, meaning their shape is altered, which affects their ability to function.

Front

What is denaturation in enzymes?

Back

Denaturation is the process where an enzyme loses its functional shape due to external stress, such as high temperature or pH changes.

Front

What are reactants in a chemical reaction?

Back

Reactants are the starting materials in a chemical reaction that undergo transformation.

Front

How do enzymes lower activation energy?

Back

Enzymes lower activation energy by providing an alternative reaction pathway, making it easier for the reaction to occur.
