Glycolysis

Question 1

where happens?

Answer 1

Cytoplasm

Question 2

Process of Glycolysis

Answer 2

Phosphorylation of glucose to glucose phosphate (using the inorganic phosphate from ATP)
Hydrolysed to 2X Triose Phosphates
2X triose phosphates oxidised to 2X pyruvate
-2 NAD reduced
-4 ATP regenerated

4 gained -2 used = net production of 2 ATP

Question 3

Process of glycolysis if no O2 present (anaerobic respiration)

Answer 3

Pyruvate converted into lactate (in animals) and ethanol (plants, yeasts)
Oxidising reduced NAD—-> Nad regenerated
So glycolysis can continue which needs NAD

Question 4

After glycolysis if O2 is present

Answer 4

Pyruvate actively transported into the mitochondrial matrix

Question 5

Stages of Aerobic respiration

Answer 5

1) Glycolysis
2) Link reaction
3) Krebs cycle
4) Oxidative phosphorylation
