QUESTION:
Some species of bacteria can live in hot springs. Their cells contain enzymes that function best at temperatures 70∘ C or higher.

How will the enzymes in these bacteria most likely change if the temperature is lowered to 45∘ C?

ANSWER:
CORRECT (SELECTED)
The enzymes will not catalyze reactions as efficiently.

EXPLANATION:
70∘ C is the optimal temperature for the bacteria's enzymes to function. A lower temperature would reduce the enzyme's efficiency in speeding up a reaction.

The enzymes of thermophilic bacteria cannot increase the rate of reactions much as at 70°C due they are naturally adapted to these conditions.

What are thermophilic bacteria?

Thermophilic bacteria are microorganisms that evolved to live in extreme heat (temperature) conditions such as observed in geysers.

Thermophilic bacteria are also called extremophiles because they can survive in extreme environmental (temperature) conditions such as those found in volcanoes and it is believed that they are the first forms of life.

The thermophilic bacteria such as Thermus aquaticus contain enzymes that are stable to high temperatures and therefore can catalyze specific chemical reactions.

In conclusion, the enzymes of thermophilic bacteria cannot increase the rate of reactions much as at 70°C due they are naturally adapted to these conditions.
