Genetic control of the enzyme concentration Covalent modification of the enzyme Allosteric control of the enzyme activity Diffusional coupling between adjacent active sites Genetic control of the enzyme concentration Covalent modification of the enzyme Allosteric control of the enzyme activity Diffusional coupling between adjacent active sites ANSWER DOWNLOAD EXAMIANS APP
Glycolysis Why does the glycolytic pathway continue in the direction of glucose catabolism? High levels of ATP keep the pathway going in a forward direction Glycolysis occurs in either direction There are essentially three irreversible reactions that act as the driving force for the pathway The enzymes of glycolysis only function in one direction High levels of ATP keep the pathway going in a forward direction Glycolysis occurs in either direction There are essentially three irreversible reactions that act as the driving force for the pathway The enzymes of glycolysis only function in one direction ANSWER DOWNLOAD EXAMIANS APP
