  1. Chapter 9 Time Line • Laboratory • Period 1: Tuesday December 9th • Period 4: Tuesday December 9th • Period 7: Wednesday December 9th • Quiz • Period 1 : Wednesday December 10th • Period 4: Thursday December 11th • Period 7: Friday December 12th • Test / Homework is due • Period 1 : Friday December 12th • Period 4: Monday December 15th • Period 7: Tuesday December 16th

  2. Homework • Tell the story of a carbon atom as it travels through Respiration, is used in photosynthesis and returns to respiration. • Your story should be • Very detailed • Explain the processes • It will be more than a few sentences!!!

  3. 6.1 – Energy for Cells ATP – adenosine triphosphate What is ATP? Free Energy = energy available to do work. endergonic reactions = reactions that absorb energy exergonic reactions = reactions that release energy

  4. Energy Relationships

  5. ____ uses the high-energy electrons form the Krebs Cycle to convert ADP to ATP • During the ____ , pyruvic acid is broken down into carbon dioxide in a series of energy extracting reactions. • _____ respiration requires Oxygen. • _____ respiration does not require oxygen • _____ is the combination of glycolysis and another pathway to release energy in the absence of oxygen. • _____ is the main electron carrier in respiration. • _____ respiration is the process that releases energy by breaking down glucose in the presents of oxygen. • Respiration begins with a pathway called ______. • A _____ is the amount of energy needed to raise temperature of 1 gram of water 1 degree Celsius. • The end product of glycolysis is 2 _________ Chapter 6 Quiz

  6. Quiz Answers • Electron Transport Chain or ETC • Krebs Cycle • Aerobic • Anaerobic • Fermentation • NAD • Cellular Respiration • Glycolysis • Calorie • Pyruvic Acid

  7. Autotrophs – Produces its own Energy / Food Heterotrophs – get energy from the food they consume Jan Van Helmont = Plants gained mass from water Joseph Priestley = 0xygen released by plants ( candle experiment) Jan Ingenhousz = Oxygen was released during the day / Light Plant produced bubbles. Julius Robert Mayer – Light energy was converted to chemical energy. Melvin Calvin = Calvin Cycle – Path of carbon to form glucose

  8. Reminders: • The tip of the flame is the hottest. Make sure the test tube is relatively close to the tip of the flame. • Make sure you use the tip of the flame from the match to light the nut. • 1ml of water = 1 gram Energy Laboratory • When you find the calories for your peanut look at the weight. • if its .5 (half) a gram then you need to divide it by the calories to find out the total calories per gram of nut. • Example: • If my peanut is .5g then the calories from that nut is only half of what a full gram would give me therefore the calories/g would be more than the experimental value. • If the calories from the experiment = 100c Then the calories per gram = 200c/g • 100c / .5g = 200 c/g • If my peanut is 1.5g then the calories from that peanut is more than what a full gram would give me therefore the calories/g would be less than the experimental value • If the calories form the experiment =100c Then the calories per gram = 66c/g • 100c / 1.5g = 66.66 c/g
