Basics of Metabolism

Catabolism

breakdown of larger molecules

anabolism

synthesis of larger molecules

Types of Energy

Kinetic Energy, heat/thermal energy, potential energy, chemical energy

First Law of Thermodynamics

energy can be transferred or transformed but neither created nor destroyed

Second Law of Thermodynamics

every energy transfer or transformation increases entropy/disorder of the universe

ATP

free energy donor for most-energy requiring processes in body such as motion, active transport, and biosynthetic reactions
