Compare and contrast chemical energy and radiant energy. Into which broad category of energy (kinetic or potential) does each fit? What are two examples of each type of energy that relate to human physiology?

Chemical energy is potential energy and radiant energy is kinetic energy. Two examples of chemical energy are triglycerides and complex carbohydrates such as glycogen. Two examples of radiant energy are UV light (a DNA mutagen) and visible light (sensed by the visual system).
