12.1 glycolysis Flashcards
1
Q
glycolysis step 1
A
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
2
Q
glycolysis step 2
A
the phosphorylated glucose molecules split into two TP
3
Q
glycolysis step 3
A
TP is oxidized- hydrogen is removed from each TP molecules to NAF to make NADH
4
Q
glycolysis step 4
A
production of ATP- TP is converted into pyruvate. as this occurs 2 molecules of ATP are regenerated from ADP and Pi
5
Q
energy yields from glycolysis
A
conversion of TP to pyruvate produces two ATP molecules each (4 in total but 2 are used up)
