6A_Respiration


 * __29 June 2010__**

1. What is the relationship between energy and matter? - Matter needs energy to perform different functions - Energy can be used to transfer matter - Matter stores energy - Potential Energy, Kinetic Particle Energy
 * Topical Essential Questions**

2. How is energy significant to biological system? - Carry out life processes - Respiration, Eating, Typing. Everything!

3. Can an organism survive without the exchange of matter with it environment? - Nope - Respiration, Photosynthesis, All life processes!

4. Are all matters living and all living organisms made of matter? - yupp

5. Can living organisms create and destroy energy? - Nooope - Energy cannot be created or destroyed

6. Can living organisms create and destroy matter? Nopeee

- Its an energy-making process - Like fire, the body needs oxygen and a fuel - Oxygen and digested food travel through the human body - End up in the same place - Blood needs to carry oxygen and food for energy to be produced/released - Also produces waste products - Carbon Dioxide - Needs to be removed - Aerobic respiration of glucose: - C6H12O6 + 6O2 --> 6CO2 + 6H20 + Energy (ATP) - The energy is released in the form of ATP - Involves 3 metabolic stages: - Glycolysis: Break down glucose (6-Carbon Molecule) into (3-Carbon) Molecule (Gain 2 ATP) (Glucose -> Pyruvate)
 * Respiration**
 * Cellular Respiration**
 * Occurs in the cytoplasm
 * Energy stored in food as glucose goes through glycolysis


 * It can occur without oxygen (Not oxygen dependant) (Anaerobic respiration)


 * ADP take one phosphate -> ATP


 * 2ATP and 2NADH + @H+ are generated from this stage


 * In cytosol/ cytoplasm

- The Krebs Cycle: Occurs in Inner membrane (Mitochondrial Matrix)
 * Smaller energy-containing molecules goes through the Krebs Cycles


 * Requires Oxygen to drive the next reaction


 * ATP is produced


 * One Pyruvate -> 1 cycle thus 1 molecule of glucose -> 2 cycle (2 times of ATP)


 * Carbon Dioxide is given off


 * 2FADH2 and 2ATP and 6NADH2 are formed -> 4+2+12=18 ATP

- Electron Transport & Oxidative Phosphorylation: Hydrogen atom from Kreb Cycle - ATP & FADH - 2 Carriers: Electron carrier and H+ or proton carrier

Mitochondria - Inner layer folded to increase surface area - Inner chamber (Matrix) - Energy transformer, transfered to ATP - CO2 diffuses out
