catalysts
B
metabolism
C
viruses
D
living
Explanation: 

Detailed explanation-1: -Like all other catalysts, enzymes are characterized by two fundamental properties. First, they increase the rate of chemical reactions without themselves being consumed or permanently altered by the reaction. Second, they increase reaction rates without altering the chemical equilibrium between reactants and products.

Detailed explanation-2: -Enzymes and activation energy A substance that speeds up a chemical reaction-without being a reactant-is called a catalyst. The catalysts for biochemical reactions that happen in living organisms are called enzymes.

Detailed explanation-3: -Enzymes are proteins that have a specific function. They speed up the rate of chemical reactions in a cell or outside a cell. Enzymes act as catalysts; they do not get consumed in the chemical reactions that they accelerate.
