Glycolysis is a defining metabolic marker in multiple biological systems. Monitoring glycolysis by measuring the extracellular flux of H+ is common, but requires correction to be quantitative and unambiguous. Here, we demonstrate how to gather and correct extracellular flux data to distinguish between respiratory and glycolytic sources of extracellular acidification.

The pentose phosphate pathway (PPP) operates in parallel with glycolysis, facilitating the metabolism of both pentoses and glucose. This pathway consists of two distinct phases: the oxidative and non-oxidative phases. While it does not directly generate ATP, the intermediates formed during the process can integrate into glycolysis, contributing to cellular energy metabolism when required.Oxidative Phase: NADPH ProductionThe oxidative phase of the pentose phosphate pathway is primarily...

Functional groups are a group of atoms with characteristic properties, which when linked to the carbon skeleton of a molecule, alter the properties of that molecule. For example, the presence of certain functional groups on a molecule will make them hydrophilic, whereas others will make them hydrophobic. These functional groups are an indispensable part of organic chemistry and important components of biological molecules, such as carbohydrates, proteins, lipids, and nucleic acids. Each...

FAQs
Glycolytic function supports cells in two linked ways: it generates ATP for immediate cellular activity and supplies metabolic intermediates that can be used in other cellular processes. Because these outputs arise in the cytosol, changes in pathway activity can influence both short-term energy availability and the broader metabolic state of a cell.
When oxygen-dependent metabolism is limited, converting pyruvate to lactate becomes important because it regenerates NAD+. This regeneration allows glycolytic reactions to continue rather than stopping when NAD+ becomes insufficient. In medical contexts, that relationship connects altered glycolytic function with lactate production during conditions in which oxygen use is constrained.
Altered glycolysis can support the growth of many cancer cells, making pathway regulation clinically relevant beyond basic energy production. Glycolytic enzymes and regulatory processes therefore become subjects of diagnosis, research, and therapeutic development. Studying these changes may help investigators relate abnormal metabolic behavior to cancer biology and identify potential intervention points.
Assessing glycolytic function helps researchers and clinicians examine how tissues meet energy demands under different conditions. The same metabolic framework can be applied to exercise-related metabolism and ischemic injury, where energy production becomes especially important. It also provides context for investigating metabolic disorders that alter normal cellular energy handling.
ATP indicates the pathway's contribution to immediate energy supply, while NADH reflects a product generated during glucose breakdown. Pyruvate marks the pathway's end product, and lactate indicates that pyruvate may be reduced when oxygen-dependent metabolism is limited. Considering these outputs together helps connect pathway activity with cellular energy status and metabolic conditions.
Changes in glycolytic function can help explain how cells respond when energy demands, oxygen availability, or metabolic regulation are disturbed. In ischemic injury, the pathway provides a framework for examining energy production under restricted oxygen-dependent metabolism. In metabolic disorders, it helps researchers investigate altered handling of glucose, ATP generation, and pathway intermediates.
