Steps 1 and 3, where ATP is being used!
The committed step of glycolysis is the reaction catalyzed by phophofructokine (PFK) converting fructose-6-phosphate into fructose-1,6- bisphosphate. The reaction is irreversible and secondly, it's the only reaction peculiar to the glycolysis.
The rate-determining step of a reaction is the slowest step in a multi-step reaction mechanism that limits the overall rate of the reaction. It is the step with the highest activation energy, and therefore, it controls how quickly the reaction proceeds. Understanding the rate-determining step can help in designing experiments and optimizing reaction conditions for desired outcomes. Identifying it often involves analyzing the reaction mechanism and the associated energy profile.
There is no cure for glycolysis because glycolysis is the first step in cellular respiration which creates energy from food for our bodies to use.
Glycolysis.
Aldolase catalyzes the cleavage of fructose 1,6-bisphosphate into glyceraldehyde 3-phosphate and dihydroxyacetone phosphate in glycolysis. This step is irreversible and serves as a regulatory point in glycolysis, controlling the flow of metabolites through the pathway.
This reaction is a phosphorylation reaction where phosphoenolpyruvate transfers a phosphate group to ADP to form pyruvate and ATP. It is catalyzed by the enzyme pyruvate kinase, an important step in glycolysis for ATP production.
The sixth step of glycolysis, which involves the conversion of fructose-6-phosphate to fructose-1,6-bisphosphate, consists of a phosphorylation reaction where ATP is used as the phosphate source. This step is catalyzed by the enzyme phosphofructokinase-1.

The first reaction in glycolysis is the phosphorylation of glucose to glucose-6-phosphate by the enzyme hexokinase. This step consumes one molecule of ATP to phosphorylate glucose, making it more reactive for subsequent steps in glycolysis.
glucose-6-phosphate . . . fructose-6-phosphate
Hexokinase catalyzes the phosphorylation of glucose to glucose-6-phosphate using ATP as a phosphate donor. This reaction is the first step in glycolysis and plays a crucial role in glucose metabolism in cells.
Glycolysis takes place in the cytosol of the cell.
Glycolysis occurs in the cytoplasm of the cell. It is the first step in cellular respiration and involves the breakdown of glucose into pyruvate, producing ATP and NADH in the process.
Glycolysis is a metabolic process that normally occurs whether or not oxygen is present. It is the first step in cellular respiration and involves the breakdown of glucose to produce energy in the form of ATP.
Fructose-6-phosphate to fructose 1,6-bisphosphate. Phosphofructokinase (PFK). Requires ATP, Mg. First majorly regulated step of glycolysis. Irreversible
Glycolysis, where 1 glucose molecule (C6H12O6) splits into 2 pyruvate (C3H6O3) and produce 2 ATP.
