Cellular Respiration

Chemical Energy & Food If I offered you a choice between $20 in cash, or a check for $20, which would you take?

Chemical Energy & Food ATP – the energy currency of the cell It’s like cash in the cell 1. All parts of the cell can use it for energy

Cellular Respiration 2. Cellular Respiration is the process that makes energy(ATP) in your body

Cellular Respiration 3. Occurs in the cytoplasm and mitochondria

Cellular Respiration Words Oxygen + Glucose  Carbon Dioxide + Water + Energy (ATP)

Cellular Respiration Chemical Formulas O2 + C6H12O6  CO2 + H2O + ATP (energy)

Does This Formula Look Familiar? O2 + C6H12O6  CO2 + H2O + ATP (energy)

Aerobic Respiration 4. Takes place when oxygen is present

Anaerobic Respiration 5. Takes place when oxygen is NOT present

If Anaerobic Step 1 = Glycolysis (no oxygen needed) Happens in cytoplasm

Glycolysis 6. Glycolysis One glucose is broken into 2 pyruvates Makes 2 ATP

Cellular Respiration Step 2 = Lactic Acid Fermentation

Step 2: Lactic Acid Fermentation occurs when NO oxygen is present 2 ATP produced

Step 2: Lactic Acid Fermentation Causes muscles to become sore because lactic acid builds up Alcohol is made when bacteria do fermentation

So If NO Oxygen (anaerobic) 4 total ATP made

If Aerobic Step 1 = Glycolysis (no oxygen needed) Still 2 ATP made

Step 2: Krebs Cycle (happens in Mitochondria) Pyruvates made in glycolysis break down more 2 ATP produced

Total So Far Glycolysis = 2ATP Krebs Cycle = 2ATP 4 total ATP

Step 3: Electron Transport Chain (needs oxygen) Electrons from Krebs cycle used to make more ATP 34 ATP produced

Total Glycolysis = 2ATP Aerobic/Anaerobic = 2ATP Electron Transport Chain = 34 ATP 38 total ATP!

Biochemical Pathway The products of photosynthesis are the reactants of cellular respiration

Energy & Exercise Quick energy – when anaerobic respiration takes place in your body, lactic acid is formed This can lead to muscle soreness Long-Term Energy – Use cellular respiration to produce energy. Exercising or activities that last for at least 15 to 20 minutes. Best form for weight control.
