Question

thermophiles
thermophiles by khan academy
some species of bacteria can live in hot springs—extreme environments where water temperatures can reach up to 130°c (over 266°f). these types of bacteria are described as thermophilic, or heat - loving.

what is likely to happen to enzyme activity if the bacteria are moved to hot springs with an average temperature of 130°c?
a it is not clear what will happen to the rate of enzyme.
b the rate of enzyme activity will remain the same.
c the rate of enzyme activity will decrease.
d the rate of enzyme activity will increase.

Explanation:

Enzymes are proteins and their activity is highly temperature - dependent. Most enzymes have an optimal temperature range. Bacteria in hot springs are thermophilic and their enzymes are adapted to high temperatures. An average - temperature enzyme is not adapted to such high temperatures. High temperatures can cause denaturation of non - thermophilic enzymes, which will increase the rate of enzyme activity initially as the molecules move faster, but then quickly lead to denaturation and loss of function.

Answer:

A. It is not clear what will happen to the rate of enzyme activity.
