glycolysis Flashcards
glycolysis
largest flux of carbon in cells, sole source of metabolic energy in mamal tissue, plants can store starch do glycolysis as well as anaerobic organisms,
phosphorylation of glycose
irreversable, catalysed by hexokinase,
anaerobic glycolysis
2 atp per molecule of glucose
complete oxidation of glucose
32 atp per glucose
starch
major source of carbs, same structure and digestion pathway as glycogen _> alpha amulase into saccarides and are hydrolysed
glycolysis forms
2 pyruvate, energy is conserved in form of ATP and NADH, taken up by glucose transporters GLUT1,
prep fase
2 ATP are invested to activate glucose, the bond between C-3 and C-4 is broken
pay off fase
C-1 is oxidised and the energy is conserved in 1 NADH and 2 ATP per triose phosphate, many reactions are reversable
NAD+ regeneration
educing pyruvate to lactate or ethanol (fermentation), a reaction prevalent under
anaerobic conditions; under conditions of sufficient [O2 ], pyruvate becomes decarboxylated and enters the
TCA cycle
