Where does the Krebs cycle occur in bacteria?

The Krebs Cycle is a complex metabolic process that takes place in the cytoplasm of eukaryotic cells and Archaea. It is a circular pathway that is responsible for the degradation of carbohydrates, fatty acids and amino acids. It allows for the production of high energy compounds such as ATP and NADPH that are used in the production of other macromolecules. However, the Krebs Cycle is not present in prokaryotes as these bacteria lack a true nucleus and a

Where does the Krebs cycle occur in eukaryotic cells?

In eukaryotic cells, the Krebs cycle occurs in the mitochondria, the cell’s energy-generating organelle. During respiration, ADP is produced from the breakdown of glucose and fatty acids. This atp is then used to power the production of more ATP. In order to regenerate NAD+, some of the NAD+ is transhydrogenated to NADPH by the action of the enzyme transhydrogenase using the electrons from the electron transport chain. Finally, the

Where does Krebs cycle occur in bacteria?

We can use the concept of the ‘universal tree of life’ to understand where the Krebs cycle occurs in bacteria. The universal tree of life is a tree-like diagram in which the different branches represent the evolutionary relationships of all known living species. The Krebs cycle is present in bacteria, archaea and eukaryotes. However, the fungal and plant kingdoms are not known to use the Krebs cycle. This means that the Krebs cycle is an example of a metabolic

Where does Krebs cycle occur in fungi?

The Krebs cycle occurs in fungi just like it does in the rest of life. However, while the Krebs cycle is part of the oxidative phosphorylation pathway in most aerobic organisms, fungi usually use fermentation to get energy. Even in humans, the Krebs cycle is not the primary way most cells produce energy. The majority of your cells use oxidative phosphorylation for energy production, which allows for the production of adenosine triphosphate (ATP) to fuel other

Where does the Krebs cycle occur in prokaryotes?

The Krebs cycle is a series of chemical reactions that allow bacteria to generate energy from food. It can be found in the cytoplasm of prokaryotes -- the region inside the cell that does not contain the cell nucleus. The two main products of the Krebs cycle are NADH and ATP. These are important for the production of energy and to support other metabolic processes within the cell.
