Krebs School (Danish: Krebs' Skole) is a private school located in Stockholmsgade in Copenhagen, Denmark. It was founded on 15 August 1872 by Conrad Peter Julius Krebs. Several members of the Danish royal family have attended the school, along with other members of the Danish upper class and nobility.

The Krebs Cycle, also known as the citric acid cycle, is the second major step in the aerobic oxidation of glucose within living organisms. Most organisms use glucose as a major fuel source, but must break down this glucose and store the energy in ATP and other molecules. Then, the cell uses this energy to power various cellular reactions, such as ...
The first step of utilizing glucose, glycolysis, produces a few ATP as well as the molecules which will be processed with the Krebs cycle. During glycolysis, a single glucose molecule is split into two smaller, three-carbon molecules called pyruvate. Pyruvate is then converted to acetyl CoA. Acetyl CoA is then utilized within the Krebs cycle to pro...
Before the first stages of the Krebs cycle, pyruvate is converted into acetyl CoA. During this process, one molecule of CO2 and one molecule of the electron carrier NADH are produced. The Krebs cycle involves converting this acetyl CoA into carbon dioxide. During the steps of the cycle, two molecules of CO2 are released, in addition to 3 more molec...
The Krebs cycle happens only within the mitochondrial matrix. Pyruvate is formed in the cytosol of the cell, then imported into the mitochondria. Here, it is converted to acetyl CoA and imported into the mitochondrial matrix. The mitochondrial matrix is the innermost part of the mitochondria. The graphic below shows the different parts of mitochond...
The mitochondrial matrix has the required enzymes and environment for the complex reactions of the Krebs cycle to take place. Further, the products of the Krebs cycle drive the electron transport chain and oxidative phosphorylation, both of which occur in the inner mitochondrial membrane. The electron carriers will dump their electrons and protons ...
Mitochondria are found in almost all organisms, especially multicellular organisms. Plants, animals, and fungi all use the Krebs cycle as an indispensable part of aerobic respiration.
The Krebs cycle has 9 main reactions, which happen quickly in succession. The image below shows these reactions.
Note that citrate is the first molecule created after acetyl CoA is added. This is why the Krebs cycle is also known as the citric acid cycle. The products of the cycle are in the image above. This process is known as a cycle because it always ends on oxaloacetate which can be combined with a new acetyl CoA to produce a new molecule of citrate for ...
The Krebs cycle is likely the most important part of the process of aerobic respiration because it drives the formation of electron carriers. These carriers are important. They carry the energy used to create a large number of ATP molecules in the final steps of aerobic respiration. The electron carriers produced (NADH and FADH2) cannot provide ene...
