Where does the Krebs cycle take place in prokaryotes?

The Krebs cycle is a series of chemical reactions that happen in the cytoplasm of the cell. It was first discovered in plants by German botanist Hans Krebs in 1926, and later also observed in bacteria and archaea, which are single-celled organisms that do not have a nucleus.

Where does the Krebs cycle occur in bacteria?

The oxidative part of the Krebs cycle takes place in the cytoplasm within the cell, while the reductive reactions occur within the enzymes of the periplasm or the cell membrane. These different compartments are connected by the intermembrane space or the space between the inner and outer cell membranes. Although the oxidative reactions of the Krebs cycle occur within the cytoplasm, the products of the Krebs cycle are usually transported to the cell membrane or the per

Where does the Krebs cycle occur in prokaryotes?

As we have seen, the Krebs cycle occurs in the cytoplasm of eukaryotes and archaea, the cells of bacteria, and involves a number of enzymes that are not found in prokaryotes. However, there are a number of bacteria that have a partial or complete Krebs cycle, including bacteria from the genera Bacillus, Clostridium, Lactobacillus, and Propionibacterium.

Where do Krebs cycle in prokaryotes occur?

Most bacteria like E. coli and B. subtilis can use the classic Krebs cycle to metabolize sugars and other sugars. However, many bacteria use a different pathway to metabolize sugars called the glycolysis pathway. This pathway is simpler and does not produce the same amount of energy. For this reason, some bacteria use the Krebs cycle and others metabolize sugar using the simpler pathway.

Where do Krebs cycle occur in prokaryotes?

Most of the species of bacteria that use the Krebs cycle use a modified version of the pathway that does not have a step requiring fumarate. This modification results in a back-end of the cycle in which some of the acetyl-CoA produced in the previous step is diverted from entering the TCA cycle to form the two-carbon metabolite butyrate. Since butyrate is an important fuel for most anaerobic organisms, such as many species of bacteria and archaea
