Glycolysis Flashcards
Site of glycolysis
Cytoplasm
Deficiency of this enzyme causes decreased muscular performance and fatigue
PFK I
Cleaves furctose 1,6-bisphosphate into GADP and DHAP
Aldolase A
Cleaves fuctose 1-phosphate into glyceraldehyde and dihydroacetone phosphate
Aldolase B
Aldolase enzyme most common in most cells
Aldolase A
Aldolase enzyme present in liver and kidney
Aldolase B
Agents that inhibit glyceraldehyde 3-phosphate dehydrogenase via inhibition of formation of thiohemiacetal
Sulfhydryl reagents
Inhibitor of glycosus as it promotes overproduction of reactive O2 species which also leads to non-formation of a thiohemiacetal
Hyperglycemia
Inhibitor of glycolysus which prevents synthesis of ATP by competing with the Pi binding site
Arsenate
The reduction of pyruvate to L lactate in the absence of O2 is coupled with the
Reoxidation of NADH to NAD+
Inhibits glycolysis by inhibiting enolase
Fluoride
Deficiency in pyruvate kinase, there is also decreased ATP synthesis in
RBCs –> alteration of shape –> increased phagocytic activity that engulf damaged RBCs –> premature death of RBCs –> hemolytic anemia
Deficient PFK results in
fatigue, low exercise tolerance
