The document summarizes the regulation of glycolysis and cyanide resistant respiration. There are three major control points in glycolysis - hexokinase, phosphofructokinase, and pyruvate kinase. Cyanide resistant respiration occurs in some plant mitochondria and allows respiration to continue in the presence of cyanide through the use of an alternative oxidase enzyme. This pathway produces heat, aids in fruit ripening, and helps with osmoregulation.

 Regulation of glycolysis  Regulation by – Hexokinase Phosphofructokinase Pyruvate kinase  Cyanide resistance respiration  Summery
 There are three major enzymatic control points within the glycolytic pathway  These include hexokinase, phosphofructokinase and pyruvate kinase
Inhibitor : Glucose-6-phosphate Activator : ADP,AMP
Inhibitor- ATP,Citrate Activator- AMP, Fructose2,6-bisphosphate
Inhibitor : ATP, Acetyl CoA, Alanine Activator : AMP
 It is a respiratory pathway occuring only in mitochondria of some plants .  This mechanism is not found in animals.  The respiration resistant to cyanide is connected with the presence in the respiratory chain of an additional terminal oxidase(AOX)
Regulation of glycolysis and Cyanide resistance respiration
 Heat production  Fruit ripening  Oxidation of NADH  Osmoregulation
Cyanide resistant respiration refers to the ability of certain organisms to survive in environments containing cyanide. This resistance in often attributed to alternative oxidases , an enzymes that bypass the cyanide sensitive step of the electron transport chain . By maintaining respiration in cyanide –rich environments, these organisms can continue to generate energy and survive.
