Presentation Transcript

  1. Do Now! 11/7/16 • Go to www.socrative.com • Join room name “PETERS216” • Complete the quiz (it is not a graded quiz) • Homework: Gummy Bear labs due Monday

  2. Gummy Lab • The type of solute did not matter (salt vs. sugar) • We are dealing with the concentration of water • Concentration of water outside the bear vs. inside the bear

  3. Distilled Water • No solute outside which means high concentration of water • Lots of solute (sugar) inside, which means lower concentration of water • Which way will water move?

  4. Salt Water • Some solute (salt) outside which means high concentration of water • Lots of solute (sugar) inside which means low concentration of water • Which way will water move?

  5. Which one had “more” Osmosis? • Salt or Distilled? • Distilled • Why? • There was a higher concentration of water outside in the distilled setup, than the concentration of water outside in the salt setup.

  6. Question: • Which of the following statements concerning diffusion and active transport is correct? • Both diffusion and active transport require cell energy. • Neither diffusion nor active transport require cell energy. • Diffusion requires cell energy while active transport does not. • Active transport requires cell energy while diffusion does not.

  7. Photosynthesis and Cellular Respiration

  8. Terms • Pigment – material that gives something its color based on what type of light it absorbs • ATP – cellular energy and is produced by cellular respiration

  9. Terms • “troph” = food • Autotrophs • Auto = self • Make their own food • Heterotrophs • Hetero = different • Get their food from something else (they have to eat it)

  10. Brain Pop • Photosynthesis

  11. Photosynthesis

  12. Photosynthesis • Process that converts the sun’s energy into chemical energy stored in sugar • Takes place in specialized structures inside plant cells called chloroplasts • Chlorophyllis the pigment that absorbs sunlight.

  13. Photosynthesis Reaction • CO2 + H2O + light energy →C6H12O6 + O2 • Where does the “light energy” come from? • The food plants make is called glucose(sugar)

  14. Photosynthesis Reaction • CO2 + H2O + light energy →C6H12O6 + O2 • Carbon Dioxide + Water + Light Energy → Sugar (Glucose) and Oxygen • Either one is fine!

  15. How do plants absorb CO2? • Stomata (plural) – pores in the leaf that allow for exchange of gas • Stoma (singular) • CO2 – in • O2 – out • How does the gas move??? • Your answer below

  16. Brain Pop • Cellular Respiration

  17. 11/9/16 • Do Now: • What 3 things are required for photosynthesis and what 2 things does it produce? • Homework: • Gummy lab due Monday • Submit Do Now document by Monday in google classroom.

  18. Cellular Respiration • Process that turns food into cellular energy (ATP) • Happens in both plantand animalcells • Occurs in the mitochondria • In the folds within (the worm)

  19. Cellular Respiration Overview • Overall Reaction: • C6H12O6 + O2 → CO2 + H2O + ATP • Glucose + Oxygen → Carbon Dioxide + Water + ATP • Energy output depends on whether or not there is oxygen • Aerobic Respiration – oxygen present • Anaerobic Respiration (fermentation) - no oxygen present

  20. Which one is better? • Oxygen rich respiration (aerobic)? • Oxygen poor respiration (anaerobic)?

  21. Runner’s Bonk • Ever felt tired when running? • https://www.youtube.com/watch?v=aYfWH960W0Q • Why??

  22. Fermentation • The process by which your body produces energy in the absence of oxygen • Produces much less ATP • Makes your muscles very sore the next day • Lactic acid fermentation • Can be used to make alcohol! • Alcoholic fermentation

  23. Energy Tally • 36 ATP for aerobic vs 2 ATP for anaerobic • Per glucose molecule • Anaerobic organisms can’t be too energetic but are important for global recycling of carbon

  24. Cycle ATP
