  1. Energy Chapter 2 section 2 www.yellowtang.org/cells.php

  2. Energy and Matter • Energy- The ability to do work or cause change. • Energy can be converted from one form to another. • Ex. Light bulb http://www.clean-energy-ideas.com/articles/pros_and_cons_of_solar_energy.html

  3. http://www.energycrysis.com/energy-crisis/general-information/diagram-a-light-bulbhttp://www.energycrysis.com/energy-crisis/general-information/diagram-a-light-bulb

  4. Energy and Matter • Free energy- the energy in a system that is available for work. • States of Matter • Solid • Liquid • Gas • Which has more energy?

  5. States of Matter http://www.ilpi.com/msds/ref/vapor.html

  6. Energy and Chemical Reactions • Chemical reactions are represented by equations. • Reactants- Shown on left side of equation • Products- Shown on right side of equation • Arrows point in which direction the equation or reaction can occur http://www.onimoto.com/p3-2.html

  7. Balanced Chemical Equation http://www.chem.ufl.edu/~itl/2045/lectures/lec_3.html

  8. Energy and Chemical Reactions • Exergonic Reactions- Chemical reactions that involve a net release of free energy. http://www.emc.maricopa.edu/faculty/farabee/biobk/biobookenzym.html

  9. Energy and Chemical Reactions • Endergonic Reactions- Reactions that involve a net absorption of free energy http://www.emc.maricopa.edu/faculty/farabee/biobk/biobookenzym.html

  10. Energy and Chemical Reactions • Activation Energy- The amount of energy needed to start a reaction http://www.chem.ufl.edu/~itl/2045/lectures/lec_m.html

  11. Energy and Chemical Reactions • Catalysts- reduce the amount of activation energy needed for a reaction • Enzymes- Class of catalysts in living things http://www.scienceclarified.com/El-Ex/Enzyme.html

  12. Reduction-Oxidation Reactions • Redox reactions- reactions in which electrons are transferred between atoms • Reduction Reactions- A reactant gains one or more electron; negative charge • Oxidation Reactions- A reactant loses one or more electron; positive charge
