Presentation Transcript

  1. Alternative Pathways in cell respiration

  2. Cell Respiration is separated into 3 stages ELECTRON TRANSPORT AND OXIDATIVE PHOSPHORYLATION KREBS CYCLE GLYCOLYSIS NADH FADH2 NADH NADH Electron transport chain... Glucose CO2 Pyruvate Krebs Cycle H2O CO2 ATP ATP ATP Energy/electrons are transferred from glucose to convert NAD+ to NADH, which is used in the ETC to make ATP

  3. I eat more than just glucose, what happens to all that stuff? Vs.

  4. Fatty acids Fats Krebs cycle Glycerol Glucose Pyruvate Acetyl CoA Sugars Carbs Proteins Amino acids NH3 The metabolism of all macromolecules is tied to cellular respiration • Carbohydrates, fats, and proteins can be broken down and used in glycolysis and the Kreb’s cycle.

  5. Cellular respiration is carefully regulated: when ATP is abundant, respiration slows down when ATP is needed, respiration speeds up

  6. The metabolism of all macromolecules is tied to cellular respiration • Excess intermediates of glycolysis and the Kreb’s cycle can be converted to stored carbohydrates, fats and proteins. Pathway for synthesis of RNA, DNA Phospholipids Fats Glycogen or starch Several intermediaries used as substrates in amino acid synthesis Fatty acids Pruvate Glucose Acetyl CoA Krebs cycle Lactate (from fermentation)

  7. I eat only fat-free foods-Why am I still getting fat?
