Glycolysis (7.4)

Question 1

State the site for glycolysis

Answer 1

Glycolysis occurs in the cytoplasm of cells

Question 2

Describe the process of glycolysis

Answer 2

ATP is hydrolysed into ADP and the phosphate is used to destabilize an intermediate 3 carbon compound (original 6 carbon glucose molecule divided into 2 molecules). Phosphate level phosphorylation occurs and ATP is formed again, and H molecules are lost and used to reduce NAD. Pyruvate us finally produced

Question 3

Explain why glucose must be phosphorylated by ATP in glycolysis

Answer 3

To destabilize it so it can be converted into pyruvate

Question 4

State the ratio of glucose to pyruvate produced in glycolysis

Answer 4

Overall, glycolysis converts one six-carbon molecule of glucose into two three-carbon molecules of pyruvate.

Question 5

State the net gain of ATP in glycolysis

Answer 5

8 ATP
