Final answer:
Phase I of the ACE IFT model refers to the "Priming Step" in Glycolysis where alpha-D-Glucose is phosphorolated at the 6 carbon by ATP via the enzyme Hexokinase to yield alpha-D-Glucose-6-phosphate (G-6-P). This step is regulated by glucose-6-phosphate.
Step-by-step explanation:
The phase I of the ACE IFT model refers to Phase 1 of Glycolysis, which is the "Priming Step." In this phase, alpha-D-Glucose is phosphorolated at the 6 carbon by ATP via the enzyme Hexokinase (Class: Transferase) to yield alpha-D-Glucose-6-phosphate (G-6-P). This step is negatively regulated by the presence of glucose-6-phosphate.
