-Extreme Changes in Temperature, Particularly Heat, Can Denature Proteins and Enzymes

Multiple Choice

-Extreme changes in temperature, particularly heat, can denature proteins and enzymes. Why might this cause a problem?

A) The denatured enzymes would speed up chemical reactions to a pace too fast for the cells.
B) The denatured enzymes would not function; thus, critical reactions would be unable to occur in the cell.
C) The denatured enzymes would not function; thus, negative feedback would be inhibited.
D) The denatured enzymes would not function; thus, the activation energy for reactions would be reduced.
