Essential Chemistry for Biology Chapter 2 1. There are 92 naturally occurring elements on Earth. What is an element? substances that cannot be broken down 2. Four of the elements oxygen, carbon, hydrogen and nitrogen make up about 96% of the weight of the human body. Oxygen is the most abundant element in the body. 3. Trace elements are required in very small amounts, but we cannot live without them. 4. Why is the trace element iodine important in the body? essential for hormone produced by thyroid gland 5. Why is the trace element fluoride important in the body? needed component of healthy bones and teeth 6. Know the chemical element for each of the following symbols: C; carbon H; hydrogen O; oxygen

ENERGY Physiology Function:worklive -grows(mitosis) -reproduce(meiosis+fertilization) -metabolism(photosynthesis and respiration) -inheritance(generation) Definition of Energy 2 Laws of Energy: 1.Conservation of Energy- energy is neither created nor destroyed, only transformed(1st law) *forms of energy: solar, potential, mechanical 2.Entropy- during the transformation of energy, some energy become disordered & becomes heat(2nd law) *heat: ?disordered energy? Coupled Reactions and Chemical Bonds *?coupled?: with partner *coupled reactions= redox reactions 1.Reduction- gains electrons -creates chemical bond -stores energy in molecule -Photosynthesis(anabolic) 2.Oxidation-loses electrons
