1. Energy can be define as the ability to do work
3. The law of conservation of energy state that energy can neither be created nor destroyed but can be change from one form to another
4. Anabolism requires energy to grow and build. Catabolism uses energy to break down
2. Potential energy is the stored energy in any object or system by virtue of its position or arrangement of parts. However, it isn't affected by the environment outside of the object or system, such as air or height. On the other hand, kinetic energy is the energy of an object or a system's particles in motion.
