Metabolism Flashcards
Catabolic pathways
breaking stuff:
Protein breakdown
Lipid oxidation
Carbohydrate oxidation
nucleotide hydrolysis
Anabolic pathways
Building stuff up (like muscle 💪 )
Protein synthesis
Lipid synthesis
Carbohydrate synthesis
Nucleotide synthesis
Oilrig
Oxidation is loss (of electrons)
Reduction is gain (of electrons)
What is glycolysis (+ when does it occur)
Oxidation from sugars
Occurs in anaerobic conditions
What is PFK
It is a regulatory rate limiting enzyme involved in glycolysis
What is PFK activated by?
AMP, Fructose 6 phosphate
What is PFK inhibited by?
ATP, lower pH and Citrate
When pyruvate moves into the mitochondria what happens?
Decarboxylated to form acetyl CoA
What is oxidation of fats called?
beta-oxidation
What does the citric acid cycle do?
Nad+ -> NADH
What is needed for the citric acid cycle to occur?
Acetyl CoA
How many molecules of pyruvate are created with molecule of glucose?
2,
Which sugar is cleaved during glycolysis from a 6 carbon sugar to 2 3 carbon sugars
Fructose 1,6 Biphosphate
What are the energu investment phases of Glycolysis (how many ATP molecules used?)
Hexokinase and phosphofructokinase
2 ATP
What are the energy generation phases in Glycolysis?
2NADH
phosphoglycerate kinase (2ATP)
Pyruvate kinase (2ATP
