Which statement explains why catalysts are important for living organisms? *
Catalysts increase the amount of product formed from limited reactants.
Catalysts cause gases to be produced at a slower rate, so cells don't burst.
Catalysts are used up during chemical reactions, so organisms must constantly make
new ones.
Catalysts allow chemical reactions to occur at temperatures at which the organism
lives.

Catalysts allow chemical reactions to occur at temperatures at which the organism lives.

Explanation:

Catalysts are molecules that speeden the rate of chemical reaction by lowering the activation energy of the reaction. In a living system, the catalyst are ENZYMES, which help to hasten up many biochemical reactions.

Another function of catalyst in living systems is that it allows chemical reactions to occur at temperatures at which the organism lives.

a compound is a molecule made of atoms from different elements.

a. by the combination of an unlimited number of elements
