Question

What will most likely happen if an enzyme is added to a chemical reaction?

a) The rate of reaction will increase.
b) The equilibrium of the reaction will be maintained.
c) The rate of reaction will decrease.
d) The reaction will stop.

Answer 1

Answer: A) The rate of reaction will increase.

Explanation: Enzymes lower the activation energies of chemical reactions; in cells, they promote those reactions that are specific to the cell's function. Because enzymes ultimately determine which chemical reactions a cell can carry out and the rate at which they can proceed, they are key to cell functionality.
