Mitochondrion structure
![Page 4: Respiration. Find the mitochondrion Mitochondrion structure](https://reader035.vdocument.in/reader035/viewer/2022062408/56649f145503460f94c286b5/html5/thumbnails/4.jpg)
Why does cell respiration matter?
• Converts all the forms of energy that we take in (food) into one form of energy for all cell processes.
Power Plant analogy

Other effects of respiration
• Source of our body temperature.
• The rate of respiration changes when we get a fever or exercise.

4 metabolic processes
• Glycolysis
• Oxidative decarboxylation
• Krebs (Citric Acid) cycle
• Electron Transport Chain/ Oxidative Phosphorylation
![Page 7: Respiration. Find the mitochondrion Mitochondrion structure](https://reader035.vdocument.in/reader035/viewer/2022062408/56649f145503460f94c286b5/html5/thumbnails/7.jpg)
Glycolysis
• Big word little meaning
• Glyco- sugar
• Lys- breakdown
![Page 8: Respiration. Find the mitochondrion Mitochondrion structure](https://reader035.vdocument.in/reader035/viewer/2022062408/56649f145503460f94c286b5/html5/thumbnails/8.jpg)
Oxidative decarboxylation
• Ox- presence of oxygen
• De – without, to lose
• Carb- carbon– Using oxygen to remove carbon results in CO2
![Page 9: Respiration. Find the mitochondrion Mitochondrion structure](https://reader035.vdocument.in/reader035/viewer/2022062408/56649f145503460f94c286b5/html5/thumbnails/9.jpg)
phosphorylation
• Adding a phosphate to a molecule. – Oxidative phosphorylation– Photo phosphorylation– ATP phosphorylates enzymes

Phases of Respiration • In cytoplasm
– Glycolysis- is UNIVERSAL
• In Mitochondria– Oxidative Decarboxylation in matrix– Kreb’s Cycle- in matrix– ETC and OP on inner membrane

Glycolysis summary
• One glucose 2 pyruvate
• two ATP are used, but four are produced, which nets 2 ATP
• 2 NAD+ are converted to NADH + H+
