Glycolysis is the first step in the breakdown of glucose to extract energy for cellular metabolism. Glycolysis consists of an energy-requiring phase followed by an energy-releasing phase.

Cellular respiration is a metabolic pathway that breaks down glucose and produces ATP. The stages of cellular respiration include glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative …

Introduction to glycolysis. Role of glycolysis in producing ATPs and NADHs and converting glucose to pyruvates.

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 …

Pyruvate is produced by glycolysis in the cytoplasm, but pyruvate oxidation takes place in the mitochondrial matrix (in eukaryotes). So, before the chemical reactions can begin, pyruvate must …

We have videos on fermentation, lactic acid fermentation, alcohol fermentation, and fermentation is all about using the pyruvates to oxidize your NADH back into NAD, so it could be re-used again, for …
