glycolysis

Question 1

name three phases of glycolysis

Answer 1

energy investing phase

splitting phase

energy generating phase

Question 2

name the steps in 1st phase

Answer 2

glucose————> glucose6phosphate

e- gluco/hexokinase

glucose 6 phosphate————> fructose6phosphate
fructose1,6
bisphosphate

e: phosphofructokinase I

Question 3

name the steps in 2nd phase….

Answer 3

fructose 1,6 bisphosphate———>
(2) glyceraldehyde 3 phosphate
< ————
e: phosphotriose isomerase

Question 4

name the steps in 3rd phase

Answer 4

2 glyceraldehyde3phosphate—–>
2) 3
phosphoglycerate 2 phosphoglycerate
2 phosphoenol pyruvate
pyruvate

e; pyruvate kinase

Question 5

how many ATPS are formed in 1st phase

Answer 5

-2

Question 6

how many ATPS are formed in 3rd phase acc. old and new calculation

Answer 6

OLD

NADPH- 3x2=6
ATP 2
ATP 2

1st phase= -2
NET ATP= 8

NEW
nadph 2.5x2 =5 
atp 2
atp 2
1st phase -2

NET ATP = 7

Question 7

regulation of glycolysis

Answer 7

hexokinase inhibited by glucose 6 phosphate

glucokinase

phosphofructokinase I

pyruvate kinase

Question 8

ATP formed in anaerobic resp are

Answer 8

2
