    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 _________________________

    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,_________________________________________________

    * 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

  • 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


    Heterotrophs (like us!)

    cannot make their own

    food -> they must

    consume plants and

    other animals to obtain


    The sun gives off

    energy in the form of

    light and heat. Plants

    are able to absorb

  • 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).
