Easy Glycolysis Pathway

Description

The 3 stages of Glycolysis
• Stage 1 is the investment stage. 2 mols of ATP are
consumed for each mol of glucose
• Glucose is converted to fructose-1,6-bisphosphate.
• Glucose is trapped inside the cell and at the same time
converted to an unstable form that can be readily cleaved
into 3-carbon units.
• In stage 2 fructose-1,6-bisphosphate is cleaved into 2 3-
carbon units of glycerladehyde-3-phosphate.
• Stage 3 is the harvesting stage. 4 mols of ATP and 2 mols
of NADH are gained from each initial mol of glucose. This
ATP is a result of substrate-level phosphorylation
• Glyceraldehyde-3-phosphate is oxidized to pyruvate
