What does the acronym "PAN" stand for in terms of glycolysis products?

The acronym "PAN" is commonly used to represent the key products resulting from the glycolysis pathway. In this case, it stands for Pyruvate, ATP, and NADH, which are all crucial outputs of this metabolic process.

During glycolysis, one molecule of glucose is broken down into two molecules of pyruvate, generating a net production of two ATP molecules through substrate-level phosphorylation. Additionally, two molecules of NADH are produced as glucose is oxidized, capturing high-energy electrons in the form of reduced NAD+. This trio of products—pyruvate, ATP, and NADH—plays a pivotal role in cellular respiration, influencing both aerobic and anaerobic pathways that follow glycolysis.

The other choices do not accurately represent the key products of glycolysis as defined by the acronym "PAN." Phosphate is a component of ATP but is not represented as a standalone product in this context, and Acetyl CoA is produced from pyruvate during the link reaction but is not an output of glycolysis itself.
