The electrical energy is transformed into this form to move the fan blades. Plug in a lamp into an electrical socket and you turn electrical energy into this form of energy. Radiant energy from the sun is turned into this form when plants undergo photosynthesis.
So, how does the human body make ATP, the only fuel it can convert to energy? Our bodies have three different chemical systems that convert energy. Most everyone knows that we use proteins, carbohydrates and fats for energy. Calories are measurement of a unit of heat or food energy. For example, we can achieve four calories per gram of proteins and carbohydrates, and nine calories per gram from fats. But how do we convert these potential energy substances into ATP? This is where three energy systems come into play. Energy System 1: Ready fuel for immediate energy . The Immediate Energy system, or ATP-PC, is the system the body uses to generate immediate energy. The energy source, phosphocreatine (PC), is stored within the tissues of the body.
