Question:
Some species of bacteria can live in hot springs. Their cells contain enzymes that function best at temperatures of 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.

Enzymes are those substances that are found to increase the rate of a biological reaction. These substances are proteins are always produced in the body. The are specific in their action so no enzyme can catalyze two reactions. This is because the enzymes are able to interact with their substrates in a lock and key model.

Now, given the fact that the enzymes that function best at temperatures of 70∘ C or higher, the efficiency of the enzyme would be highly reduced if the temperature of the surrounding is reduced to about 45∘ C.
