Question

Quizplus · Accepted Answer

Most metabolic pathways contain irreversible steps, especially those pathways that are critical for the regulation of metabolism, such as glycolysis and the citric acid cycle. These irreversible steps are often points of regulation, allowing the cell to control the flow of metabolites through the pathway.
