  1. Glycolysis | Cellular respiration | Biology (article) | Khan Academy

    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.

  2. Steps of glycolysis (video) - Khan Academy

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

  3. Overview of glycolysis (video) - Khan Academy

    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 …

  4. Steps of cellular respiration | Biology (article) | Khan Academy

    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 …

  5. Overview of glycolysis (video) | Glycolysis | Khan Academy

    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 …

  6. Pyruvate oxidation | Cellular respiration (article) | Khan Academy

    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 …

  7. Glycolysis (practice) | Respiration | Khan Academy

    Test your knowledge on the process of glycolysis!

  8. Overview of cellular respiration (video) | Khan Academy

    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 …

  9. Krebs / citric acid cycle (video) | Khan Academy

    Video transcript So we already know that if we start off with a glucose molecule, which is a 6-carbon molecule, that this essentially gets split in half by glycolysis and we end up 2 pyruvic …

  10. Glycolysis | Cellular respiration | Biology (article) | Khan Academy

    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.
