Enzymes

Front

What is the active site of an enzyme?

Back

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

Front

What does it mean for an enzyme to be highly specific?

Back

It means that each enzyme only catalyzes one specific reaction or acts on a specific substrate.

Front

What are products in the context of enzyme reactions?

Back

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

Front

What happens to enzymes when they are heated to high temperatures?

Back

The shape of the enzyme changes, leading to denaturation, which means the enzyme can no longer function properly.

Front

What is an enzyme?

Back

An enzyme is a biological catalyst that speeds up chemical reactions in living organisms without being consumed in the process.

Front

What is the role of substrates in enzyme activity?

Back

Substrates are the reactants that enzymes act upon to facilitate a chemical 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

How do enzymes lower activation energy?

Back

Enzymes lower activation energy by providing an alternative reaction pathway and stabilizing the transition state.

Front

What is the significance of enzyme concentration in reactions?

Back

Increasing enzyme concentration generally increases the rate of reaction, provided there is enough substrate available.

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.
