Glycolysis

Question 1

where does glycolysis occur

Answer 1

cytosol

Question 2

roles of glycolysis

Answer 2

• to break down carbohydrate to generate energy
• to provide building blocks (intermediates) to synthesis other compounds
• conversion of 6C glucose to 2 x 3C pyruvate
• requires niacin (B3) as NAD
• production of (NADH+ H+) and 2 ATP

Question 3

2 phases of glycolysis

Answer 3

1st phase (energy investment stage): 1 x glucose -> 2 x glyceraldehyde-3-phosphate

2nd phase (energy harvesting stage): 2 x glyceraldehyde-3-phosphate -> 2 x pyruvate
