12.1 glycolysis

Question 1

is glycolysis an aerobic or anaerobic reaction?

Answer 1

anaerobic

Question 2

where does glycolysis occur?

Answer 2

cytoplasm of all living cells

Question 3

describe the process of glycolysis. (4)

Answer 3

1) glucose is phosphorlyated with 2 Pi from hydrolysis of ATP
-> activates glucose & lowers Ea for enzyme controlled reactions

2) phosphorylated glucose is split into 2 * TP

3) TP is oxidised & H atoms is added to NAD to form reduced NAD

4) TP is converted to pyruvate & 2 ATP is generated for each molecule

Question 4

what is the net production for each glucose molecule?

Answer 4

2 ATP
2 pyruvate
2 reduced NAD

Question 5

what is the definition of respiration?

Answer 5

controlled release of energy from food
