Respiration- Glycolysis Flashcards
What is the 1st step of glycolysis?
Phosphorylation
what does phosphorylation involve?
glucose (6C) is phosphorylated by 2 ATP to form fructose bisphosphate (6C)
What is the 2nd step of glycolysis?
Lysis
What does lysis involve?
fructose bisphosphate (6C) splits into two molecules of triose phosphate (3C)
What is the 3rd step of glycolysis?
Oxidation
What does oxidation involve?
hydrogen is removed from each molecule of triose phosphate and transferred to coenzyme NAD to form 2 reduced NAD
What is the 4th step of glycolysis?
Dephosphorylation
What does dephosphorylation involve?
phosphates are transferred from the intermediate substrate molecules to form 4 ATP through substrate-linked phosphorylation
What is the 5th step of glycolysis?
Production of pyruvate
Why is pyruvate prodyced?
It is used in the next stage of respiration
Why is glycose phosphorylated?
-It makes glucose more reactive
-Glucose phosphate cannot pass through the cell membrane
Where does glycolysis take place?
Cytoplasm
What is the main function of glycolysis?
Phosphorylation and splitting of glucose
What are the products of glycolysis?
2 pyruvate and NADH
