Question

An enzyme in an arctic fish has an optimal temperature range of approximately 4∘ Celsius. If an enzyme from the arctic fish is put inside a Amazonian fish whose average body temperature is approximately 30∘ Celsius what would happen to the rate of enzymatic reactions for that enzyme?

Answer 1

Placing an enzyme from an arctic fish with an optimal temperature of 4° Celsius into an Amazonian fish with a body temperature of 30° Celsius would likely decrease enzymatic reaction rates and could lead to the enzyme's denaturation due to the higher temperature.

Step-by-step explanation:

If an enzyme in an arctic fish with an optimal temperature of approximately 4° Celsius is placed inside an Amazonian fish with a body temperature of about 30° Celsius, the rate of enzymatic reactions for that enzyme would likely decrease. This is because enzymes are adapted to function optimally within a specific temperature range, and a significant deviation from this range affects their activity. In this case, the arctic enzyme is adapted to cold temperatures and would not function well at the higher temperatures found in the Amazonian fish.

The enzyme could become less active and might even denature, leading to a loss of its three-dimensional structure and function. This thermal stress could disrupt the chemical bonds within the enzyme's active site, making it less effective at catalyzing reactions.
