Presentation Transcript
1. Cellular Respiration • The breakdown of glucose into ATP
2. Mitochondria & Cellular Respiration
3. Mitochondria & Cellular Respiration Found in Both Plants & Animals
4. Mitochondria & Cellular Respiration Found in Both Plants & Animals Breaks down GLUCOSE into ENERGY
5. Mitochondria & Cellular Respiration Found in Both Plants & Animals Breaks down GLUCOSE into ENERGY Chemical formula is the same as photosynthesis but in reverse
7. Cellular Respiration Foldable Create a pyramid foldable this will go on page 49 Use the foldable to complete your notes
8. Glycolysis • Happens in the cytoplasm (cytosol) of the cell • We put in 2 ATP to start the process • We make 4 ATP and break the glucose down into 2 molecules of pyruvate Since we paid 2 ATP up front to start the process we only Gained 2 ATP From glycolysis we get - 2 ATP - 2 pyruvate - 2 NADH (goes to ETC) Pyruvate now travels to the mitochondria
9. The Krebs Cycle / Citric Acid Cycle • Occurs inside the mitochondria • Is an aerobic process, NEEDS OXYGEN to work • Breaks down the pyruvate into acetyl-CoA • Net yield of 2 ATP • Net yield of 6 NAHD & 2 FADH2 (this will help run the next process) • Releases Carbon dioxide as waste
10. Electron Transport Chain • Final stage of Cellular Respiration • Takes place in the mitochondria • Electrons are released from NADH & FADH 2 as they pass through the inner mitochondrial membrane, as they go through electrons give up energy to create 28-32 ATP • Hydrogen is also combined with Oxygen to form water
