Chapter 16 + 17

Question 1

Hexokinase

Answer 1

Phosphorylates glucose

Question 2

Phosphoglucose isomer add

Answer 2

Converts glucose 6 phosphate into fructose 6 phosphate

Question 3

Phosphofructokinase

Answer 3

Forms fructose 1 6 bisphosphate

Question 4

Aldolase

Answer 4

Cleaves fructose 1 6 bisphosphate

Question 5

Triode phosphate isomerase

Answer 5

Catalyze the inter conversion of 3 carbon isomers

Question 6

Goyceraldehyde 3 phosphate dehydrogenase

Answer 6

Generates the first high phosphoryl transfer that is not ATP

Question 7

Phosphoglycerate

Answer 7

Generates first molecule ATP

Question 8

Phosphoglycerate mutate

Answer 8

Converts 3 phosphoglycerate into 2 phosphoglycerate

Question 9

Enolase

Answer 9

Generate second high phosphoryl transfer potential not ATP

Question 10

Pyruvate kinase

Answer 10

Generates second molecule ATP

Question 11

In fermentation what is donor and acceptor

Answer 11

Glyceraldehyde 3 phosphate is donor

Pyruvate in lactic and acetylaldehyde in alcohol are acceptors

Question 12

Why is glucokimase important

Answer 12

When max ATP hexokinase inhibited and want to still make and store

Question 13

Why do we need niacin

Answer 13

Make NAD+

Question 14

Why can’t we reverse glycolysis

Answer 14

Some reactions are far to exergonic

Question 15

What is fate of puruvate

Answer 15

Ethanol lactic acid

H20 CO2

Question 16

What is effect of lactic acid buildup

Answer 16

Lower pH highly acidic

Question 17

What does fructose 2 6 bisphosphate do in terms of allosteric

Answer 17

Stabilizes R state

Question 18

Why can’t we just run glycolysis in reverse

Answer 18

Highly endergonic steps

Question 19

What generates pyruvate

Answer 19

Protein
Lactate
Glycerol

Question 20

Pyruvate carboxylase

Answer 20

Generates oxaloacetate

Question 21

Acetyl coA

Answer 21

Required for pyruvate carboxylase activity

Question 22

Phosphoenolpyruvate carboxykinase

Answer 22

Generate high phosphoryl transfer potential compound

Question 23

Glycerol

Answer 23

Readily converted to DHAP

Question 24

Fructose 1 6 bisphosphotase

Answer 24

Gluconeogenic counterpart of PFK

Question 25

Glucose 6 phosphatase

Answer 25

Found predominantly in liver

Question 26

Why does gluconeogenesis occur during exercise

Answer 26

Lactic acid is produced and need to get rid of it as highly acidic so liver removes and turns to pyruvate and makes glucose to use or store as glycogen

Question 27

How many high energy molecules are required to synthesize one molecule of glucose for 2 molecules pyruvate

Answer 27

4 ATP 2 GTP 2 NADH

Question 28

Glycolysis goes when

Answer 28

High AMP
High fructose 2 6 bisphosphate
Increase insulin
Fed

Question 29

Gluconeogenesis goes when

Answer 29

High ATP
Increase citrate 
Increase acetyl coA
Increase glucagon
