When a piece of liver is dropped into hydrogen peroxide, the peroxide bubbles vigorously as the hydrogen peroxide (H2O2) decomposes. However, if the liver is cooked first, the reaction fails to occur. The reason for this is

a. heating kills the germs that cause the bubbling

b. heating damages the enzyme in liver that breaks down hydrogen peroxide

c. heating removes the water and oxygen from the liver

d. reactions take place faster at lower temperatures
