    AP Biology Unit 2: Storing, Converting, and Releasing Free Energy

    Homework Sept. 17-18
    • Watch the first 3 videos below
    • Take notes in your new note packets.
    Homework Sept. 19-22
    • Finish the classwork/homework assignment "Metabolism" (attached below)
    • Prepare for a quiz on Monday "Intro to Metabolism and Enzymes" - see calendar and use the videos below
    • Go to this page ENZYME LAB follow the instructions and complete Pre-lab items 1-7. (Turn in via google document)
    • Optional - Complete any test corrections - Re-write the question then give the correct answer with a rationale to show understanding to recover .25pts/question. (please submit this via a shared google doc - titled correctly) The following questions are not eligible for credit because we discussed in class and I threw them out (# 11, 32, 40, 42, 48) - You MAY correct multiple choice questions as well.

     

    Homework for Sept. 23 -24
    • Watch the first photosynthesis video, "overview" (see below)
      • Then go to this page (Photosynthesis Lab) and follow the instructions. Complete pre-lab items 1- 6 and brainstorm #7. (turn in #1-6 via google document.)
    • Work on Photosynthesis Preview homework. - You may need to preview the other photosynthesis videos below.
    • Prepare for a discussion on photosynthesis next class.
     Homework for Sept. 25-26
    • Watch the photosynthesis videos 2-5 below - work on your note packets while watching
    • Prepare for Big Photosynthesis Quiz - which will be take home or online - TBD
    Homework for Sept. 27-29
    • Preview Cellular Respiration and Fermentation with your note packets and the videos found below
    • Complete the Respiration/Fermentation Preview assignment (shared google document). - follow the included instructions
    Homework for Oct. 1-2
    • Finish reviewing the Respiration and Fermentation Videos while working on your note packets
    • Respiration Lab - Go to this link for the respiration lab and work through the prelab links so you can answer the prelab questions. We will discuss this more in class.
     
    Homework for Oct. 3-7
  • Finish Respiration Lab - Post Lab write up.  Use the sample data if necessary. Turn in via Google Docs (make sure to title correctly)
  • Complete the handout given in class for a homework grade - "Resp/ferm quiz and test overflow questions" - I will have a review session to go over this Monday at lunch.
  • Study for Unit 2 Exam - it will be similar in structure to the first exam.  Don't forget to review metabolism, enzymes, photosynthesis, respiration and fermentation.

    An Introduction to Metabolism
     
     
     
     
      Essential Questions:
    • How are materials moved into and out of cells to maintain homeostasis?
    • How does free energy organize life?
    • How is energy stored in living systems?
    • How is energy transferred within and between living systems?
    • How are energy transfers facilitated in living systems?
    • How do cells modify and control metabolic activities?
    • How is sunlight energy captured and converted into chemical bond energy.
    • How is chemical bond energy of fuel molecules release in manageable amounts and forms?
      Objectives:
    • Describe passive and active transports across the cell membrane.
    • Discuss how relative concentration gradients and water potential play a role in transport across selectively permeable membranes
    • Describe how energy is stored and released from chemical bonds.
    • Define the laws of thermodynamics and discuss how they apply within living cells.
    • Define free energy and discuss how life depends on the availability of free energy.
    • Illustrated the ATP / ADP + P + energy cycle.
    • Discuss energy coupling.
    • Explain the function and limitations of enzymes.
    • Highlight the relationship between the structure of the enzyme and its functioning.
    • Discuss metabolic control.  (feedback)
    • Emphasize plant and other photosynthetic organisms’ role in the overall energy systems of living things on earth.
    • Explain the processes of photosynthesis in detail.  Relating the processes to the previous discussion on energy.
    • Explain chemiosmosis in detail.  How do the structures and properties of membranes play a role in this process?
    • Illustrate the cyclic nature and interdependence of these processes.
    • Discuss and illustrate alternative pathways for carbon fixation in plants.
    • Describe fermentation and respiration in detail.
    • Relate the processes of respiration to photosynthesis.
    • Discuss the role of these energy releasing pathways to the interdependence of organisms.
    • Highlight the role enzymes and membranes, free energy, and properties of water play in these processes.
    Activities, Readings and Viewings:
    • Read Campbell chapters 6, 10, and 9
    • Video Tutorials
    • Diffusion/Osmosis Lab
    • Enzyme Lab
    • Photosynthesis Lab I
    • Photosynthesis Lab II
