Enzymes

Front

What are enzymes?

Back

Enzymes are proteins that act as biological catalysts, speeding up chemical reactions in cells.

Front

What is the role of enzymes in chemical reactions?

Back

Enzymes lower the activation energy required for a reaction to occur, making it easier for the reaction to take place.

Front

What is activation energy?

Back

Activation energy is the minimum energy required for a chemical reaction to occur.

Front

How does temperature affect enzyme activity?

Back

Enzymes have an optimal temperature at which they function best; too high or too low temperatures can reduce their activity.

Front

What is the optimal temperature for the enzyme discussed in the questions?

Back

30°C is the optimal temperature for the enzyme.

Front

What is pH and how does it affect enzymes?

Back

pH is a measure of acidity or alkalinity; enzymes have an optimal pH range and deviations can affect their activity.

Front

What is the optimal pH for the enzyme discussed in the questions?

Back

The optimal pH for the enzyme is 9.

Front

What is a substrate in relation to enzymes?

Back

A substrate is the specific reactant that an enzyme acts upon.

Front

How does the shape of an enzyme relate to its function?

Back

The shape of an enzyme is specifically designed to fit certain substrates, allowing it to catalyze specific reactions.

Front

What happens to enzymes after a reaction?

Back

Enzymes are not consumed in the reaction; they can be reused multiple times.
