- Respiration
- Glycolysis
- Occurs in the Cytoplasm
- Glucose is broken down into two molecules of Pyruvate.
- Pyruvate molecules then move into the mitochondrial matrix for the link reaction
- The overall net yield of ATP for this stage of respiration is two molecules of ATP
- Four molecules of reduced NAD are also produced
- The Link Reaction
- Pyruvate molecules then move into the mitochondrial matrix for the link reaction
- Pyruvate is converted into Acetyl CoenzymeA with the addition of a coenzymeA group
- Acetyl CoenzymeA (2C) combines with Oxaloacetate (4C) to form Citric Acid (6C)
- The Electron Transport Chain
- They are split into their H+ ions and their electrons and the energy from the movement of these ATP is produced
- The Krebs Cycle
- Acetyl CoenzymeA (2C) combines with Oxaloacetate (4C) to form Citric Acid (6C)
- Many molecules of reduced NAD and FAD are formed
- These then enter the electron transport chain
- The Electron Transport Chain
- They are split into their H+ ions and their electrons and the energy from the movement of these ATP is produced
- The Electron Transport Chain
- These then enter the electron transport chain
- Glycolysis
