phosphoglycerate kinase

glyceraldehyde-3 -dehydrogenase

UTP-glucose

glucose-6-P

glucose-1-P

UDP-glucose

The pathway oxidizes two moles of NADH to NAD+ for each mole of glucose that enters

The pathway requires two moles of ATP to get started catabo-lizing each mole of glucose

ADP is phosphorylated to ATP via substrate level phosphorylation

The pathway does not require oxygen
