Glycolysis Flashcards
Where does glycolysis occur?
cytoplasm
In what type of cells does glycolysis occur?
liver muscle and adipose tissue
When is pyruvate converted to lactate?
In an anaerobic state
Can fructose enter into the glycolytic pathway?
Yes at Fructose 6 - Phosphate and at Fructose 1 -Phosphate
Describe a substrate level phosphorylation step
It occurs in 1-3 bis p glycerinate to 3 - phosphate glycerinate and from Phospho enol pyruvate to pyruvate where ATP is formed by a phosphate donor which ADP receives
What is required to get glucose inside the cell?
insulin
How much glucose should remain outside the cell?
70-100 ml/dl (serum glucose)
cofactor is
mineral
coenzyme is
vitamin
What amino acid can pyruvate be converted to?
alanine
What is the pathway that occurs by which glucose is degraded into 2 units of pyruvate?
glycolysis
glycolysis is important because it provides the initial sequence of reactions necessary for the complete oxidation of
glucose via the krebs cycle
the hexokinase and glucokinase reaction consumes
1 mol ATP/mol glucose
what is modulated negatively by ATP and citrate
phosphofructokinase
phosphofructokinase is positively modulated by
AMP and ADP
