Which of the following best explains how enzymes speed up a chemical reaction? enzymes question 3 options: can add heat to a chemical reaction. remove heat from a chemical reaction. lower the activation energy of a chemical reaction. are not changed as a result of a chemical reaction.

The correct answer is: ENZYMES LOWER THE ACTIVATION ENERGY OF A CHEMICAL REACTION.

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy
