Chapter 6—Energy Flow in the Life of a Cell I. What is energy a. Energy can be defined as the capacity to do work i. There are 2 types of energy 1. Kinetic energy a. Energy of movement b. Includes light (movement of photons), heat (movement of molecules),  electricity (movement of electrically charged particles) c. Under the right conditions it can be transformed into potential energy 2. Potential energy a. Stored energy b. Includes chemical energy stored in the bonds that hold atoms together in  molecules, electrical energy stored in a battery, and positional energy  stored in a diver poised to spring II. The Laws of Thermodynamics Describe the Basic Properties of Energy a. Define the basic properties and behavior of energy b. The first law of thermodynamics i. Assuming there is no influx in energy, the total amount of energy within a given system  remains constant ii. Energy can neither be created nor destroyed iii. Energy can change form 1. Chemical energy heat energy iv. AKA the law of conservation of energy c. The second law of thermodynamics i. When energy is converted from one form to another, the amount of useful energy  decreases ii. Energy can be converted into less useful heat such as when driving a car iii. Regions of concentrated energy tend to be highly ordered
