Flashcards in 21 - Gluconeogenesis Deck (23):
1

enzymes involved in oxidative decarboxylation

isocitrate dehydrogenase, alpha ketoglutarate dehydrogenase, pyruvate dehydrogenase

2

starving for one day recruits blank

glucagon

3

stress response of starvation after 1 day recruits these hormones

epinephrine, cortisol

4

beta blocker inhibitts these and can lead to hypoglycemia

glucagon and epinephrine

5

alcohol consumption inhibits blank and can lead to hypoglycemia

gluconeogenesis

6

major glucose precursor in gluconeogenesis

lactate

7

lactate becomes pyruvate via blank enzyme

lactate dehydrogenase

8

two cycles of gluconeogenesis

cahill cycel (glucose alanine), cori cycle (glucose lactate)

9

pyruvate becomes oxaloacetate via pyruvate carboxylase as long as there is blank present from fatty acids

acetyl coA

10

carboxylation and decarboxylation require blank

energy

11

glucose 6 phosphatase and pepck are not in the blank

muscle

12

if there is an overexpression of pepck and it is in the muscle, then blank fibers take over in massive amounts and blank greatly increases

type 1, endurance

13

glyuconeogenesis is blank in reverse

glycolysis

14

anaplersosis is blank

filling up

15

acetyl coA is blank anaplerotic in mammals because theree is no blank

not, net gain

16

dextrin is involved in bacterial blank

adhesion

17

bacteria have isocitrate lyase and malate synthase produce a net gain of malate so it is blank

anaplerotic

18

fructose 2,6 bisphosphate inhibits blank

fructose 1,6 bisphosphate

19

fructose 2,6 bisphosphate regulation of pfk 1 reaction

feed forward

20

inborn error of gluconeogenesis leads to blank

hypoglycemia

21

substrate cycling is involved in non shivering blank

thermogenesis

22

deregulated substrate cycling increase results in excessive blank

heat production

23

glucose undergoes blank to become co2

oxidative decarboxylation
