GS Enzymes: Friday

Front

What is an enzyme?

Back

A biological catalyst that speeds up chemical reactions in living organisms.

Front

What is the role of sucrase in the reaction involving sucrose?

Back

Sucrase is the enzyme that catalyzes the breakdown of sucrose into glucose and fructose.

Front

How do enzymes affect activation energy?

Back

Enzymes lower the activation energy required for a reaction to occur.

Front

What happens to enzymes at extreme pH levels?

Back

Enzymes can denature, losing their functional shape and activity.

Front

What is denaturation in the context of enzymes?

Back

Denaturation is the process where an enzyme loses its structure and function due to external factors like pH or temperature.

Front

What is the optimal pH for most enzymes?

Back

Most enzymes have an optimal pH around neutral (pH 7), but this can vary.

Front

What does a catalyzed reaction graph look like compared to a non-catalyzed reaction?

Back

A catalyzed reaction graph shows a lower activation energy peak compared to a non-catalyzed reaction.

Front

What is the significance of the 'Red' line in enzyme-catalyzed reactions?

Back

The 'Red' line typically represents the energy profile of a catalyzed reaction, showing lower activation energy.

Front

What is the significance of the 'Blue' line in enzyme-catalyzed reactions?

Back

The 'Blue' line usually represents the energy profile of a non-catalyzed reaction, showing higher activation energy.

Front

What factors can affect enzyme activity?

Back

Temperature, pH, substrate concentration, and enzyme concentration can all affect enzyme activity.
