What substances are responsible for accelerating chemical reactions in cells?

Answer 1

The substances which cause chemical reactions in a cell are protein catalysts called enzymes. Some cause reactions that would otherwise not occur and others speed reactions up. Carbon dioxide dissolves in water by itself but since this a dangerous substance to have in cells, there is a catalyst that dissolves it 300 times faster.

Answer 2

Enzymes are the catalysts for chemical reactions. They are capable of speeding them up and slowing them down when necessary.

Answer 3

A catalyst increases the rate of a chemical reaction. In cells these are called enzymes. They do not enter into the reaction nor are changed by it.

Answer 4

Chemical reactions in living things are usually speeded up by catalysts called enzymes.

Answer 5

catalyst or enzyme.
