Enzymes

Front

What is an enzyme?

Back

A biological catalyst that speeds up chemical reactions in living organisms without being consumed in the process.

Front

What is a substrate?

Back

The substance on which an enzyme acts during a chemical reaction.

Front

What is the active site of an enzyme?

Back

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

Front

What happens to enzymes at high temperatures?

Back

The shape of the enzyme changes, leading to denaturation, which can render the enzyme inactive.

Front

What is denaturation in enzymes?

Back

The process in which an enzyme loses its three-dimensional structure, resulting in loss of function.

Front

What are reactants?

Back

Substances that undergo a chemical change in a reaction.

Front

What are products in a chemical reaction?

Back

The substances that are produced as a result of a chemical reaction.

Front

How do enzymes lower activation energy?

Back

Enzymes provide an alternative reaction pathway with a lower activation energy, making it easier for the reaction to occur.

Front

What is the role of temperature in enzyme activity?

Back

Temperature affects the rate of enzyme activity; each enzyme has an optimal temperature range.

Front

What is the effect of pH on enzyme activity?

Back

Each enzyme has an optimal pH range; deviations can lead to decreased activity or denaturation.
