An enzyme is a special kind of catalyst. How does it work?

a
It slows down specific chemical reactions.
b
It triggers chemical reactions at any pH or temperature.
c
It breaks down and takes part in chemical reactions to form new products.
d
It speeds specific chemical reactions.

d. It speeds specific chemical reactions.

Enzymes work by lowering the activation energy needed for a specific chemical reaction to occur, leading to a faster rate of reaction. They do not get consumed in the reaction and can be used multiple times. Enzymes are highly specific, meaning they only catalyze one particular reaction or a small group of similar reactions.
