  2. Catalyst: • How do you get energy for you cells from the sun???

  3. 8-1: Energy and Life • Energy is the ability to do work • How do you get energy for you cells from the sun??? • The answer involves 3 type of energy SUN ATP GLUCOSE

  4. ATP • ATP is the type of energy that cells can use • AdenosineTriphosphate (ATP) Adenine base 3 phosphate groups Ribose sugar

  5. Worksheet review • ATP is the type of energy that cells can use • AdenosineTriphosphate (ATP) Energy Storing Reaction

  6. ATP is the type of energy that cells can use • AdenosineTriphosphate (ATP) Energy Releasing Reaction

  7. How do you get energy for you cells from the sun??? SUN ATP GLUCOSE

  8. How do you get energy for you cells from the sun??? respiration photosynthesis SUN ATP GLUCOSE

  9. 8-2: Photosynthesis • In the presence of light, carbon dioxide and water is transformed into carbohydrate and oxygen. CO2 = carbon dioxide H2O = water C6H12O6 = glucose (carbohydrate) O2 = oxygen

  10. Review: Chemical Reactions CO2 + H2O C6H12O6+ O2 What are the products? What are the reactants?

  11. Photosynthesis CO2 + H2O C6H12O6+ O2 • This process occurs in the chloroplast and can occur because of the pigment chlorophyll. • A pigment is a protein molecule that can absorb light energy. reactants products

  12. The principal pigment in plants is • A. chlorophyll. • B. oxygen. • C. ADP. • D. ATP. • E. NADPH.

  13. The principal pigment in plants is • A. chlorophyll. • B. oxygen. • C. ADP. • D. ATP. • E. NADPH.

  14. In which organelles would chlorophyll pigments be found? • A. vacuoles • B. centrioles • C. mitochondria • D. chloroplasts • E. ATP

  17. Which equation best summarizes the process of photosynthesis? • A. • B. • C. • D. • E.

  18. Which equation best summarizes the process of photosynthesis? • A. • B. • C. • D. • E.

  19. In a typical plant, all of the following factors are necessary for photosynthesis EXCEPT • A. chlorophyll. • B. light. • C. oxygen. • D. carbon dioxide. • E. water.

  20. In a typical plant, all of the following factors are necessary for photosynthesis EXCEPT • A. chlorophyll. • B. light. • C. oxygen. • D. carbon dioxide. • E. water.

  21. Analyzing Data pg 213

  22. Factors Affecting Photosynthesis and Plant Adaptations • Water • Waxy cuticle on plants in dry climates reduces water loss • Temperature • Enzymes needed for photosynthesis work best 0-30oC • Intensity of Light • Plants work best in range of light intensity

  23. Fall Colors • In the fall, because of changes in the length of daylight and changes in temperature, the leaves stop their food-making process. The chlorophyll breaks down, the green color disappears, and the yellow to orange colors become visible and give the leaves part of their fall splendor. • http://www.esf.edu/pubprog/brochure/leaves/leaves.htm

  24. How do you get energy for you cells from the sun??? respiration photosynthesis SUN ATP GLUCOSE

  25. CH 9-1: Chemical Pathways • Calorie: amount of energy needed to raise the temperature of 1 gram of water 1 degree C

  26. CH 9-1: Chemical Pathways • Food Energy the cell can use (ATP) • First step = glycolysis • Can then be completed with or without oxygen • Aerobic Respiration • Anaeronic Respiration ATP GLUCOSE

  27. Making ATP

  39. Energy Glucose and Oxygen Sunlight ? ? ATP Carbon dioxide and Water

  40. Energy Glucose and Oxygen Sunlight Photosynthesis Cellular Respiration ATP Carbon dioxide and Water

  41. Energy Organelles • Mitochondria and Chloroplast both have shapes with high surface area to volume ratios to increase membrane space for reactions to occur • Both evolved from prokaryotes by the process of endosymbiosis • Both have DNA separate from nuclear DNA • In humans, all mDNA inherited from mother • Both have membrane proteins more similar to bacteria than the cells membrane • Both reproduce independently of cell
