An enzyme is a special kind of catalyst. How does it work? a It speeds specific chemical reactions. b It slows down specific chemical reactions. c It triggers chemical reactions at any pH or temperature. d It breaks down and takes part in chemical reactions to form new products.

Answer 1

The correct answer is a: It speeds specific chemical reactions.

Enzymes are biological catalysts that facilitate and accelerate chemical reactions in living organisms by lowering the activation energy required for the reactions to occur. They are specific to the reactions they catalyze, meaning each enzyme typically acts on a particular substrate and is influenced by factors such as pH and temperature.
