Where does Krebs cycle occur in prokaryotes and eukaryotes?

Because the Krebs cycle is so important to energy production, it’s not surprising that it also occurs in both archaea and Eukarya (eukaryotes). There are a few ways to tell that this is the case. Firstly, each organism that uses the Krebs cycle has enzymes that are specific to the cycle. This is a strong indicator that the cycle was present in their common ancestor. There are also other pieces of evidence that support the idea that the Krebs cycle was

How does Krebs cycle occur in pro

The Krebs cycle occurs in all living organisms, including bacteria, plants, and animals. Its function is to break down sugars, which are the energy source for aerobic respiration The Krebs cycle takes place in the cytoplasm and the enzymes that carry out the process are called the Krebs cycle enzymes.

How does Krebs cycle occur in prokaryotes and eukaryotes?

In eukaryotes, the Krebs cycle takes place in organelles called mitochondria, which were first discovered in the 1840s by German biologist Christian Wilhelm Krebs. Mitochondria are responsible for generating chemical energy in the form of adenosine triphosphate (ATP). This energy is used in the body for metabolism, breathing, muscle contraction, and brain activity. The Krebs cycle performs the same function in all eukayotes, and thus its name is associated

How does Krebs cycle occur in eukaryotes?

Most eukaryotic cells have a complete Krebs cycle in the mitochondria. The presence of the Krebs cycle in the mitochondria is necessary for the generation of energy in the form of ATP. Cells that don’t have a complete Krebs cycle in the mitochondria can still metabolize glucose to pyruvate, however, the energy produced is much less than if the complete Krebs cycle were present. Some parasites (like trypanosomes) and other organisms (like

How does Krebs cycle occur in prokaryotes?

The Krebs cycle is a part of the tricarboxylic acid (TCA) cycle that takes place in the cytoplasm of most eukaryotic cells (as it is their main energy source) as well as in the periplasm of prokaryotes. In addition, the Krebs cycle is present in the mitochondria of eukaryotic cells, too, which are responsible for the energy production. It is named for German biochemist Hans Kre
