Let's explore the process of glycolysis, the first phase of cellular respiration. Learn how this process breaks down glucose into two 3-carbon compounds, using two ATPs in the investment phase and …

Learn the steps of cellular respiration, including glycolysis, citric acid cycle, and oxidative phosphorylation, on Khan Academy's detailed guide.

How pyruvate from glycolysis is converted to acetyl CoA so it can enter the citric acid cycle. Pyruvate is modified by removal of a carboxyl group followed by oxidation, and then attached to Coenzyme A.

Glycolysis, which is the first step in all types of cellular respiration is anaerobic and does not require oxygen. If oxygen is present, the pathway will continue on to the Krebs cycle and oxidative …

Fermentation and cellular respiration begin the same way, with glycolysis. In fermentation, however, the pyruvate made in glycolysis does not continue through oxidation and the citric acid cycle, and the …

Now that we have a very high-level overview of glycolysis, let's get a better appreciation for exactly what's going on. And whenever I look at these more detailed processes, the one thing to just …
