glycolysis (cellular respiration)
glycolysis
NAD i reduced
glucose----2 pyruvate
net production: 2 ATP
4 stages:
-phosphorylation
-splitting of hexose 1,6 biphosphate
-oxidation of triose phosphate
-conversion of the intermediate to pyruvate
key words
NAD: nicotinamide adenine dinucleotide(coenzyme)
reduced: H added
oxidised: H lost
1.phosphorylation
changes glucose molecule
-unable to leave cell through glucose transporters
maintains glucose concentration
-for diffusion of glucose
3.glucose to a higher energy level
-unstable
-more reactive
-easier to split
oxidation of triose phosphate
2x triose phosphate-----> 2x intermediate compound
2x ATP (by substrate level phosphylation)
dehydrogenase enzyme removes 2 H atoms from each triose phosphate molecule
give H atoms to NAD
triose phosphate has been oxidised (lost H)
NAD has been reduced (gained H)
splitting of hexose 1,6 biphosphate--(h2o)--> 2x triose phosphate
conversion of intermediate to pyruvate
-series of enzyme controlled reactions
-2x ATP formed by substrate level phosphorylation
2x intermediate compound--2 ATP-->2 pyruvate
products of glycolysis
2 reduced NAD
2 ATP
2 pyruvates
