Khan Academy Cellular respiration involves many steps, which can be divided into three main stages: glycolysis, the citric acid cycle (also called the Krebs cycle), and the electron transport chain. Glycolysis takes place in a cell’s cytosol.
Krebs / citric acid cycle - Khan Academy Overview of the Krebs or citric acid cycle, which is a series of reactions that takes in acetyl CoA and produces carbon dioxide, NADH, FADH2, and ATP or GTP.
Overview of cellular respiration (video) | Khan Academy The Krebs cycle occurs in the mitochondrial matrix, where pyruvate is turned into acetyl-CoA, which then goes through a series of reactions, producing ATP, NADH, and FADH2. Finally, oxidative phosphorylation uses NADH and FADH2 to create a …
Oxidative phosphorylation - Khan Academy Overview of oxidative phosphorylation. The electron transport chain forms a proton gradient across the inner mitochondrial membrane, which drives the synthesis of ATP via chemiosmosis.
Cellular respiration introduction - Khan Academy There are three stages to cellular respiration: glycolysis, the Krebs cycle, and the electron transport chain. Cellular respiration is the process by which cells derive energy from glucose. The chemical reaction for cellular respiration involves glucose and oxygen as inputs, and produces carbon dioxide, water, and energy (ATP) as outputs.
Glycolysis - Khan Academy Each step is catalyzed by its own specific enzyme, whose name is indicated below the reaction arrow in the diagram below. Step 1. A phosphate group is transferred from ATP to glucose, making glucose-6-phosphate.
The citric acid cycle - Khan Academy Overview and steps of the citric acid cycle, also known as the Krebs cycle or tricarboxylic acid (TCA) cycle.
Pyruvate oxidation - Khan Academy The point of pyruvate oxidation is the generation of acetyl-CoA which is used by the Krebs cycle. 2. Krebs cycle takes place in the matrix of mitochondria, and that's why pyruvate oxidation takes place in the matrix of mitochondria.
Steps of cellular respiration - 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.
Krebs / citric acid cycle - Khan Academy Overview of the Krebs or citric acid cycle, which is a series of reactions that takes in acetyl CoA and produces carbon dioxide, NADH, FADH2, and ATP or GTP.
