- Glycolysis
- General info
- 1st stage of aerobic and anaerobic repiration
- Happens in the cytoplasm
- Does not require any organelle or membrane
- 6-Carbon sugar is split into 3-Carbon Pyruvate
- Net gain
- 2 ATP
- 4 made, 2 used
- 2 reduced NAD
- 2 Pyruvate
- 2 ATP
- Anaerobic
- Takes place with or without oxygen
- Stage 1
- Phosphorylation
- Glucose is made more reactive
- Activated
- Lowers the activation energy for the other reactions
- Addition of two phosphate molecules
- From the hydrolysis of 2 ATP molecules to ADP.
- Glucose is made more reactive
- Phosphorylation
- Stage 2
- Splitting of the phosphorylated glucose
- 6-Carbon glucose is split into two triose phosphates
- These are 3-Carbon molecules
- 6-Carbon glucose is split into two triose phosphates
- Splitting of the phosphorylated glucose
- Stage 3
- Triose phosphate is oxidised
- Hydrogen is removed
- Transferred to coenzyme NAD
- Forms reduced NAD
- Hydrogen is removed
- Triose phosphate is oxidised
- Stage 4
- Enzyme controlled reactions
- Triose phosphate converted to pyruvate
- 2 molecules of ATP produced for each triose phosphate
