Glycolysis Has Two Steps. The First Step Is The Energy Investment Where _____ Is Used To Activate The Glucose Molecule.. The energy investment phase and the energy harvesting phase (see figure below). Glycolysis consists of two distinct phases.
Glycolysis consists of two distinct phases: The energy investment phase and the energy harvesting phase (see figure below). Atp molecules donate high energy phosphate groups during the two phosphorylation steps, step 1 with hexokinase and step 3 with phosphofructokinase, in the first half of glycolysis.
