Study Notes
Glycolysis Pathway
- Cells transform sugars like glucose into biochemical energy in the form of ATP through the glycolysis pathway.
Glycolysis Overview
- The final product of glycolysis is pyruvate.
- Glycolysis involves 10 enzymatic reactions.
Purpose and Regulation
- The purpose of glycolysis in the cell is to convert glucose into energy.
- The step catalyzed by phosphofructokinase-1 is an irreversible reaction.
Reactions and Products
- The product of the lyase (Fructose bisphosphate aldolase) reaction in glycolysis is fructose-1,6-bisphosphate.
- 2 ATP molecules are consumed in the first two steps of glycolysis.
- The step that produces NADH is the glyceraldehyde-3-phosphate dehydrogenase reaction.
- 2 NADH molecules are produced in glycolysis.
Next Steps and ATP Production
- After glycolysis, the next steps for producing more ATP are the citric acid cycle and oxidative phosphorylation.
- In step 7 of glycolysis, glyceraldehyde-3-phosphate is formed.
- The phosphoglycerate mutase reaction (step 8) involves a mutase reaction.
- In step 9 of glycolysis, 3-phosphoglycerate is formed.
- The phosphofructokinase-1 reaction (step 1) involves a kinase reaction that is irreversible.
- 2 pyruvate molecules are formed for each glucose broken down in glycolysis.
ATP's Role
- ATP is consumed in the early stages of glycolysis and produced in the later stages.
- The entry of glucose 6-phosphate at the 2nd step does not affect the number of ATPs produced by glycolysis.
- Glycogen can be broken down into glucose 1-phosphate, which enters glycolysis at the 2nd step.
Products and Aerobic Respiration
- The products of glycolysis that can be used in aerobic respiration to produce more energy are NADH, FADH2, and pyruvate.
- ATP is produced in the final step of glycolysis.
