  • 2. 

    The oxygen produced during photosynthesis comes from the breakdown of carbon dioxide.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    Pt. 1: The equation for photosynthesis is 6CO2 + 6H2O —> C6H12O6 + 6O2 (or carbon dioxide and water > in the presence of sunlight > gives glucose and water) When the water breaks down(H2O), that's where the oxygen comes from (O2). I asked her what the carbon dioxide is for, and she said it's to make carbohydrates (or sugar in this case).

  • 3. 

    Water and dissolved minerals move up the xylem of the plant via capillary action.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    PT. 2: "Water with dissolved minerals moves up xylem via capillary action"

    Rate this question:

  • 4. 

    Sunlight energy is capture by...

    • Grana

    • Chloroplasts

    • Chlorophyll

    • Mesophyll

    Correct Answer
    A. Chlorophyll
    Explanation
    PT. 1: "They act like an antenna to absorb the light (photons of energy)."

    Rate this question:

  • 5. 

    Is this equation for aerobic or anaerobic? C6H12O6 + 6 O2  → 6 CO2 + 6 H2O + energy

    • Aerobic

    • Anaerobic

    Correct Answer
    A. Aerobic
    Explanation
    "Aerobic: C6H12O6 + 6 O2 → 6 CO2 + 6 H2O + energy"
    Remember anaerobic has NO oxygen and uses ONLY glycolysis (process when there is no oxygen to get some ATP)

    Rate this question:

  • 6. 

    Walls of the xylem are negatively charged and "pull up" the water by _____________ charged hydrogen atoms. 

    • Positively 

    • Negatively 

    Correct Answer
    A. Positively 
    Explanation
    PT. 2: "Walls of xylem tubes are negatively charged and “pull” up the water molecules by the positively charged hydrogen atoms."

    Rate this question:

  • 7. 

    The organelle involved in cellular respiration is the mitochondria.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    PT. 2: "Takes place in cytoplasm and mitochondria"

    Rate this question:

  • 8. 

    Fermentation is another name for anaerobic respiration.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    PT. 2: "Anaerobic (without air/oxygen) Cellular Respiration (fermentation)"

    Rate this question:

  • 9. 

    Cellular respiration is the breakdown of ATP and occurs in all living cells.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    PT. 2: "Cellular Respiration = The breakdown of sugars to ATP (useable energy) (energy molecule)"

    Rate this question:

  • 10. 

    Cellular respiration is the ________ of photosynthesis. (HINT: not the same but...)

    Correct Answer
    opposite, opposite ,
    Explanation
    PT. 2: "Cellular respiration = The breakdown of sugars to ATP"
    "Photosynthesis = making of sugar"

    Don't worry about this :) This is the process for cellular respiration. Just type whatever you want int the box when your done.   1ST PROCESS FOR CELLULAR RESPIRATION FOR BOTH AEROBIC/ANAEROBIC RESPIRATION : Place: Cytoplasm Glycolysis process - absence of oxygen (fermentation) <harvesting electrons> Glucose broken down to Pyruvic acid > NADH (electron carriers > gets the electrons) > Gives 2 ATP but not enough   2ND PROCESS NOW FOR JUST AEROBIC PROCESS (ANAEROBIC STOPS): Place: Mitochondria Pyruvic acid moves into mitochondria > gets changed to acetyl-CoA (Why does it change? oxidizes > because oxygen present)   3RD STEP: Place: Mitochondria still Moves into the Krebs cycle (9 stages)> get more electrons out > electrons get carried by NADH and FADH2 (both electron carriers)   4TH STEP: Place: Electron Transport Chain NADH and FADH2 pass their electrons deeper into the mitochondrial membrane (squiggly line thingy in the middle) into the electron transport chain (drives the process to create/synthesize the most ATP possible) FINAL: 36/38 net ATP to use for EACH glucose molecule

  • 12. 

    Don't worry about this :) This is explaining how much ATP is made in each process of cellular respiration. Just type whatever you want int the box when your done. 1 glucose molecule: Fermentation = 2 net ATP Aerobic rep. = 30+ net ATP (makes wayyyy more ATP than just fermentation)
