glycolysis

Question 1

preparative phase of glycolysis

what ? (4 things)

Answer 1

glucose –> glucose-6-phosphate –> fructose-6-phosphate –> fructose-1,6-BISphosphate

Question 2

what in the enzyme for glucose –> glucose-6-phosphate

Answer 2

hexokinase

glucokinase

Question 3

what is the enzyme for the first step of glycolysis

Answer 3

hexokinase

glucokinase

Question 4

which are the steps that use atp in glycolysis

Answer 4

glucose–> glucose6phosphate

fructose6phosphate–> fructose 1,6, BISphosophate

Question 5

what is the rate determining step of glycolysis

Answer 5

fructose 6 phosphate–> fructose 1,6,BISphospahte

phosphofructokinase

Question 6

what is the rate limiting enzyme

Answer 6

phosphofructokinase

Question 7

overall, how many atp produced/ used by glycolysis

Answer 7

2 used (preparative phase) , 4 made (ATP generating phase)

so… 2 PRODUCED OVERALL

Question 8

what is the atp generating phase

Answer 8

fructose-1.6.BISphosphate –> 2x triose phosphate– –> – – > 2 x pyruvate

Question 9

pyruvate synthesis enzyme

Answer 9

pyruvate kinase

Question 10

glucose –> how many pyruvate?

Answer 10

2

Question 11

how is adp recycled to atp

with what enzyme

Answer 11

2 x adp –> atp + amp

adenylate kinase

Question 12

what is produced in fed state/ high insulin

what effect does this have on rate of glycolysis

by doing WHat to what ENzyme

Answer 12

fructose-2,6- phosphate

increases glycolysis rate

as it allosterically activates the enzyme phosphofructose kinase (that causes fructose-6-phosphate –> fructose-1,6-BISphosphate in preparitive stage)

Question 13

nadh created/ used in glycolysis??

Answer 13

2x nadh created (atp generating phase)
