B) Elevated body temperatures may denature enzymes. This would interfere with the cell's abilities to catalyze various reactions.
C) Elevated body temperatures will increase the energy of activation needed to start various chemical reactions in the body. This will interfere with the ability of enzymes to catalyze vital chemical reactions.
