  • Cellular Respiration/Photosynthesis Note Packet

    Heterotrophs and autotrophs go through the process of cellular respiration to

    _______________________________________________________________________

    Before autotrophs go through the process of cellular respiration they have to go

    through the process of _____________________________________________________

    ________________________________________________________________________

    The energy that is released during cellular respiration is packaged in the form of

    _______________________________________________________________________

    *During cellular respiration, glucose combines with oxygen to produce carbon dioxide and

    water (and ATP). Write the chemical equation below:

    *For heterotrophs (like us!) the ____________________ comes from the food we eat.

    *The respiratory system carries

    ____________________ to the

    circulatory system. The circulatory

    system in turn, carries

    _____________________ to every cell

    in the human body.

    *Oxygen is able to

    __________________ into the cell

    while carbon dioxide ______________

    out of the cell.

    *Once inside the cell, oxygen moves

    into the _________________________

  • Cellular Respiration

    Glycolysis -> First Step in cellular respiration

    * Glycolysis takes place in the_____________________. During glycolysis, _____________

    __________________________________________________________________________

    * 4 ATP molecules are formed; however, glycolysis requires 2 ATP to break apart each

    molecule of glucose. Therefore,_________________________________________________

    __________________________________________________________________________

    * ATP stands for_____________________________________.

    * The bond linking the last phosphate group is a

    ______________________________.When the third

    phosphate is removed and bonded to another compound,

    __________________________________________________

    _________________________________________________.

  • ___________________________________, glycolysis leads to two other pathways; the

    ________________________________and the______________________________________.

    -> this is an aerobic pathway.

    Krebs Cycle & Electron Transport Chain

    * The final two stages of cellular respiration take place in the________________________.

    * During the Krebs cycle and the Electron Transport Chain,__________________________

    __________________________________________________________________________.

    Fermentation

    * If oxygen is NOT present,____________________________________________________.

    -> this is an anaerobic pathway

    * No ATP is produced during fermentation; thus,___________________________________

    __________________________________________________________________________

    Alcoholic Fermentation -> produces ethyl alcohol and carbon dioxide

    Examples __________________________________________________________

    Lactic Acid Fermentation -> produces lactic acid and carbon dioxide

    Examples __________________________________________________________

    Anaerobic ___________

    *The Krebs cycle occurs in the

    Review of Cellular Respiration

    True/False

    1) Cellular respiration that is carried out without oxygen is aerobic. __________

    2) Glucose serves as a reactant during cellular respiration. __________

    3) Heterotrophs obtain glucose as a product of photosynthesis. ___________

    4) During cellular respiration, energy is produced in the form of ATP. ___________

    5) The electron transport chain occurs during aerobic respiration. ___________

    6) Glycolysis takes place in the mitochondria. ___________

    7) The process that breaks a glucose molecule in half is fermentation. ___________

    8) During aerobic respiration, the majority of ATP is made in the mitochondria. __________

    9) Anerobic respiration is more efficient than aerobic respiration at making ATP. __________

    10) Yeast cells undergo fermentation. _________

  • Photosynthesis

    Where does all of the energy needed to sustain life come from? _________________________

    The arrows below indicate _________________________________________.

    Autotrophs are ___________________________________________________________

    ________________________________________________________________________

    Heterotrophs are _________________________________________________________

    ________________________________________________________________________

    *The following equation summarizes the process of photosynthesis.

    Carbon Dioxide + Water Glucose + Oxygen

    Details of photosynthesis

    * The process of photosynthesis begins _____________________________________________

    ____________________________________________________________________________.

    * The most important photosynthetic pigment in plants is ________________________ : this

    is what gives plants a green color.

    During photosynthesis,

    autotrophs (like plants)

    use the sunlight to

    produce their own food

    (glucose).

    Heterotrophs (like us!)

    cannot make their own

    food -> they must

    consume plants and

    other animals to obtain

    glucose.

    The sun gives off

    energy in the form of

    light and heat. Plants

    are able to absorb

    sunlight.

    Sunlight

  • Summary of Photosynthesis

    1.___________________________ inside the chloroplasts absorbs photons of light. (a photons

    is__________________________________________________________).

    2. The energy is used, along with carbon dioxide, to blow water apart.

    3. ________________________is produced.

    4. ________________________is released.

    *More specifically, chlorophyll is found within the

    _________________________________________.

    * Chlorophyll is found in the ________________________ -> an organelle found only in plant cells.

    Internal Leaf Structure

    Mesophyll Cell

  • How does photosynthesis relate to cellular respiration?

    *Photosynthesis and cellular respiration are______________________________________.

    Photosynthesis uses the energy of sunlight to produce sugars.

    The same sugars in turn serve as food (for both authotrophs and heterotrophs).

    3) Photosynthesis used the energy from sunlight to produce water and carbon dioxide.

    _________

    4) Photosynthesis occurs in the mitochondria. __________

    5) It makes sense to talk to your plants. __________
