Glycolysis 101: The Simple Yet Essential Pathway to Cellular Energy

Glucose enters the cell through facilitated diffusion or active transport.

G3P and DHAP are then converted into 1,3-bisphosphoglycerate (1,3BPG) and glyceraldehyde-3-phosphate dehydrogenase.

Q: Can glycolysis be used for energy production in the absence of oxygen?

Glycolysis 101: The Simple Yet Essential Pathway to Cellular Energy

Glycolysis is a series of 10 enzyme-catalyzed reactions that convert glucose into pyruvate, generating energy in the form of ATP and NADH. This pathway is the first step in cellular respiration and occurs in the cytosol of cells. Here's a simplified overview:

A: The key enzymes involved in glycolysis are hexokinase/glucokinase, phosphoglucose isomerase, aldolase, triosephosphate isomerase, glyceraldehyde-3-phosphate dehydrogenase, phosphoglycerate kinase, phosphoglycerate mutase, and pyruvate kinase.

Common Misconceptions

A: Glycolysis occurs in all cell types, including muscle cells, nerve cells, and other tissues.

Pyruvate is then converted into acetyl-CoA, which enters the citric acid cycle (also known as the Krebs cycle).
