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 __________________________________________________________ Aerobic ____________ Anaerobic ___________ *The Krebs cycle occurs in the _______________________________________ *The electron transport chain occurs in the _______________________________________ without oxygen with oxygen Glycolysis 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). Cellular respiration __________________________________________________ __________________________________________________________________ ________________________________________________during photosynthesis. Review of Photosynthesis True/False 1) Heterotrophs can produce their own food. __________ 2) The chemical equation for photosynthesis is the opposite of the chemical equation for cellular respiration. __________ 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. __________
