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 a substrate?

Back

A substrate is any substance that is acted upon by an enzyme during a chemical reaction.

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 do enzymes typically end with?

Back

Enzymes typically end with the suffix '-ase', such as in 'lactase' or 'amylase'.

Front

What is the enzyme-substrate complex?

Back

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

Front

What are products in an enzymatic reaction?

Back

Products are the substances that are produced as a result of an enzymatic reaction.

Front

What role do coenzymes play in enzymatic reactions?

Back

Coenzymes are non-protein molecules that assist enzymes in catalyzing reactions, often by carrying chemical groups between enzymes.

Front

How do temperature and pH affect enzyme activity?

Back

Enzymes have optimal temperature and pH ranges; deviations can lead to decreased activity or denaturation.

Front

What is enzyme specificity?

Back

Enzyme specificity refers to the ability of an enzyme to select and catalyze a specific substrate among many.

Front

What is denaturation in the context of enzymes?

Back

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