Glycolysis Why does the glycolytic pathway continue in the direction of glucose catabolism? There are essentially three irreversible reactions that act as the driving force for the pathway Glycolysis occurs in either direction High levels of ATP keep the pathway going in a forward direction The enzymes of glycolysis only function in one direction There are essentially three irreversible reactions that act as the driving force for the pathway Glycolysis occurs in either direction High levels of ATP keep the pathway going in a forward direction The enzymes of glycolysis only function in one direction ANSWER DOWNLOAD EXAMIANS APP
Glycolysis Which of the following is not true of glycolysis? ADP is phosphorylated to ATP via substrate level phosphorylation The pathway requires two moles of ATP to get started catabo-lizing each mole of glucose The pathway oxidizes two moles of NADH to NAD+ for each mole of glucose that enters The pathway does not require oxygen ADP is phosphorylated to ATP via substrate level phosphorylation The pathway requires two moles of ATP to get started catabo-lizing each mole of glucose The pathway oxidizes two moles of NADH to NAD+ for each mole of glucose that enters The pathway does not require oxygen ANSWER DOWNLOAD EXAMIANS APP
