Explain what happens when hypothermia sets in (when enzymes get too cold!)
Scorpion4ik [409]

Answer:

The shape of an enzyme also depends on its temperature. When enzymes get too warm, they get too loose. And when they get too cold, then they get too tight. <u> Since the function of this enzyme depends on its temperature, the chemical reaction will only take place when the temperature is just right.</u>
