12.1 glycolysis

Question 1

glycolysis step 1

Answer 1

glucose is activated by phosphorylation- two ATP molecules are used so that two inorganic phosphate molecules can bind onto the glucose molecules making it more reactive

Question 2

glycolysis step 2

Answer 2

the phosphorylated glucose molecules split into two TP

Question 3

glycolysis step 3

Answer 3

TP is oxidized- hydrogen is removed from each TP molecules to NAF to make NADH

Question 4

glycolysis step 4

Answer 4

production of ATP- TP is converted into pyruvate. as this occurs 2 molecules of ATP are regenerated from ADP and Pi

Question 5

energy yields from glycolysis

Answer 5

conversion of TP to pyruvate produces two ATP molecules each (4 in total but 2 are used up)
