Enzymes

Front

What are enzymes?

Back

Enzymes are biological catalysts that speed up chemical reactions in living organisms. They are primarily made of proteins.

Front

What happens to enzymes at high temperatures?

Back

Enzymes can denature, meaning their shape is altered, which can affect their function.

Front

What does substrate specificity mean in enzymes?

Back

Substrate specificity refers to the ability of an enzyme to choose exact substrate molecules. This is determined by the shape of the enzyme and the substrate.

Front

What is the active site of an enzyme?

Back

The active site is the region on the enzyme where the substrate binds and the reaction occurs.

Front

What are products in an enzyme-catalyzed reaction?

Back

Products are the substances that are produced as a result of the enzyme-catalyzed reaction.

Front

What is denaturation in enzymes?

Back

Denaturation is the process where an enzyme loses its functional shape due to external factors like heat or pH changes.

Front

Can enzymes be reused after a reaction?

Back

Yes, enzymes can be reused multiple times after catalyzing a reaction.

Front

What factors can affect enzyme activity?

Back

Factors include temperature, pH, substrate concentration, and the presence of inhibitors or activators.

Front

What is the role of enzymes in metabolism?

Back

Enzymes facilitate metabolic reactions by lowering the activation energy required for the reaction to occur.

Front

What is an enzyme inhibitor?

Back

An enzyme inhibitor is a substance that decreases the activity of an enzyme by binding to it.
