Cellular Respiration STUDENT NOTES B-3.2| Date:
|Cellula|Cellular respiration is a process that takes place mostly in the mitochondria of the cell. |
|r | |
|Respira|What is the ultimate goal of cellular respiration? |
|tion | |
| | |
| | |
| |ANY organic food molecule or nutrient can be used as a source of energy for ATP. |
| |What do these organic molecules include? |
| | |
| | |
| | |
| |Nutrients + oxygen ( water + carbon dioxide + energy (ATP) |
| | |
| |What is the equation for cellular respiration? |
| | |
| | |
| |What is interesting about this equation? |
| | |
|Mitocho| |
|ndria |The mitochondria is the main organelle involved in cellular respiration. |
| | |
| |Where do we find mitochondria? |

|Types | |
|of |What is cellular respiration’s main function? |
|cellula| |
|r |Cellular respiration occurs in 2 conditions: |
|respira| |
|tion |_______________________________ cellular respiration requires oxygen. |
| | |
| | |
| |_______________________________ cellular respiration occurs when no oxygen is present. |
| | |
| | |
| |The first stage of both aerobic and anaerobic respiration is ______________________________. |
| | |
| |Where does glycolysis take place? |
|Aerobic|To transfer the energy stored in glucose to the ATP molecule, a cell must break down _______________________ |
|cellula|slowly and capture the energy in stages |
|r |Aerobic cellular respiration has 3 stages. What are the 3 stages? |
|respira|________________________________________________ |
|tion- |Series of reactions using enzymes that takes place in the __________________________________ |
|REQUIRE|Glucose is broken down into… |
|S |________________________________________ (sometimes called pyruvate) |
|OXYGEN |________________________________________ |
| |Where does the glucose come from for Animals? __________________________________ |
| |Where does the glucose come from in Plants? ____________________________________ |
| |What is the purpose of glycolysis? |
| | |
| |________________________________________________ (also called the citric acid cycle) |
| |Takes place in the _______________________________________ |
| |Main Reactant of Krebs Cycle = ___________________________________ |
| |Where does this reactant come from? |
| | |
| |Main Products of Krebs Cycle = Carbon dioxide (CO2) and energy (in the form of 2 ATP molecules and FADH2 and NADH) |
| |What is the purpose of the Krebs Cycle? |
| | |
| |Pyruvic acid ( carbon dioxide + water + energy (2 ATP) |
| | |
| |________________________________________________ (ETC) |
| |Takes place in the _______________________________________ |
| |Main ETC Reactant = __________________________________ |
| |Other Reactants = FADH2 and NADH (from Krebs Cycle) |
| |Main Products = ______________________________________________________ |
| |What is the purpose of ETC |
| | |
| |How many ATP molecules are produced with the ETC? _________________ |
|Total | |
|glucose|During aerobic cellular respiration… |
|yield | |
| |ONE molecule of glucose will make ______________ ATP molecules! |
| | |
| |Glycolysis ATP: Kreb’s ATP: ETC’s ATP: |
| | |
| |This ATP will begin to do work in the cell. |
