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
- 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 investment phase and generating a net of two ATPs in the payoff phase
- Steps of glycolysis (video) - Khan Academy
Introduction to glycolysis Role of glycolysis in producing ATPs and NADHs and converting glucose to pyruvates
- Glycolysis (practice) | Respiration | Khan Academy
Test your knowledge on the process of glycolysis!
- Krebs citric acid cycle (video) | Khan Academy
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 acids or two pyruvate molecules
- Oxidative phosphorylation | Biology (article) | Khan Academy
Two net ATP are made in glycolysis, and another two ATP (or energetically equivalent GTP) are made in the citric acid cycle Beyond those four, the remaining ATP all come from oxidative phosphorylation
- 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 must enter the mitochondrion, crossing its inner membrane and arriving at the matrix
- 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 cycle, and oxidative phosphorylation
