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 macromolecule category do enzymes belong to?

Back

Enzymes are proteins.

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 is an active site?

Back

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

Front

What is a substrate?

Back

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

Front

What are products in an enzymatic reaction?

Back

Products are the molecules that result from the enzymatic reaction after the substrate has been transformed.

Front

Do all enzymes have an optimal pH?

Back

Yes, every enzyme has an optimal pH at which it is most active.

Front

What is the role of enzymes in chemical reactions?

Back

Enzymes speed up reactions by lowering the activation energy required for the reaction to occur.

Front

What happens to enzymes at high temperatures?

Back

High temperatures can denature enzymes, altering their structure and rendering them inactive.

Front

What is denaturation in the context of enzymes?

Back

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