Glycolysis

Question 0

What are the 6 stages of glycolysis?

Answer 0

1. Glucose is phosphorylated into Glucose-6-Phosphate using ATP (ATP is dephosphorylated into ADP + Pi).
2. Glucose-6-Phosphate is isomerised into Fructose-6-Phosphate.
3. Fructose-6-Phosphate is phosphorylated into Hexose1,6-bisphosphate using ATP (ATP is dephosphorylated into ADP + Pi).
   
   • -> substrate level phosphorylation.
4. Hexose 1,6-bisphosphate is split into two molecules of Triose Phosphate.
5. Triose Phosphate is dephosphorylated (ADP is phosphorylated into ATP) and dehydrogenated/oxidised into an intermediate compound. NAD is reduced by H+ into NADH.
6. ADP is phosphorylated into ATP converting the intermediate compound into Pyruvate
   
   • -> substrate level phosphorylation.

Question 1

Where does glycolysis take place?

Answer 1

Cytoplasm

Question 2

What are the products made from glycolysis?

Answer 2

• 2x ATP (made 4 used 2)
• 2x NADH
• 2x Pyruvate

NADH and Pyruvate are ACTIVELY TRANSPORTED into the MITOCHONDRIA.
