Verified step by step guidance

Understand the context of glycolysis: Glycolysis is a metabolic pathway that converts glucose into pyruvate, releasing energy and producing ATP. It consists of 10 steps, each catalyzed by specific enzymes.

Identify reaction 3 in glycolysis: Reaction 3 involves the conversion of fructose-6-phosphate to fructose-1,6-bisphosphate. This step is catalyzed by the enzyme phosphofructokinase-1 (PFK-1).

Recognize the substrate and product: In reaction 3, the substrate is fructose-6-phosphate, and the product is fructose-1,6-bisphosphate. This reaction is a phosphorylation process where a phosphate group is added.

Understand the role of ATP: During this reaction, ATP is used as a phosphate donor, converting to ADP in the process. This is an important regulatory step in glycolysis.

Note the significance of the reaction: Reaction 3 is a key regulatory step in glycolysis, often referred to as the 'committed step,' because it commits the substrate to continue through the glycolytic pathway.
