Unformatted text preview: Biology 230 Jennifer Breckler Lecture 1 Metabolism and the Energy of Life Chap. 8 (Campbell 8e) Major concepts 1) Energy of Life and forms of Energy 2) Chemical reactions and free energy 3) ATP structure and function 4) Enzyme structure and function Life is highly organized...i.e. plant root Becoming and staying organized requires ! Life involves transferring energy from one form to another form . For example, chemical energy in food fuels biological processes. Here are the laws of energy transfer or transformation (The Laws of Thermodynamics): 1st law: Energy in the universe is transferred (energy is not created and not destroyed). 2nd law: Energy transfers cause a release of some useless energy (i.e. heat), thus, the universe is becoming more random To stay alive, all PLANT AND ANIMAL cells constantly transfer energy in order to keep the cell ordered. ATP is an important energy transfer molecule we will learn about....
