Enzyme Activity and Temperature

What happens to enzyme activity as the temperature decreases?

• It increases due to faster molecular movement.

• It becomes zero immediately.

• It remains constant regardless of temperature.

• It decreases because molecules move slower.

Why do enzymes not follow the general rule of reactions speeding up with temperature?

• Enzymes require a specific pH to function.

• Enzymes are not involved in chemical reactions.

• Enzymes are not affected by temperature changes.

• Enzymes denature at high temperatures, losing their activity.

What is the consequence of enzyme denaturation?

• The enzyme becomes a different protein.

• The enzyme changes its substrate.

• The enzyme becomes more active.

• The enzyme loses its ability to catalyze reactions.

At extremely low temperatures, why might enzyme activity not reach zero?

• The solution might not freeze, allowing some activity.

• Enzymes become more stable at low temperatures.

• Enzymes are not affected by temperature.

• Enzymes change their structure to adapt.

What is the optimal condition for enzyme activity?

• No specific condition is required

• Low temperature and high pH

• High temperature and low pH

• Optimal temperature specific to each enzyme
