In the mitrochondria!
The Krebs cycle occurs in the mitochondrial matrix of the cell.The kreb cycle takes place in the matrix of the mitochondria.
when oxygen is not present
The Krebs cycle takes place in the matrix of the mitochondria.
Most of the Krebs cycle enzymes occur in the mitochondrial matrix, which is the space enclosed by the inner membrane of the mitochondria. This is where the majority of the reactions in the Krebs cycle take place to generate energy in the form of ATP.
The Krebs cycle, also known as the citric acid cycle or TCA cycle, occurs twice for each molecule of glucose that is metabolized. This is because one glucose molecule is broken down into two pyruvate molecules during glycolysis, and each pyruvate enters the Krebs cycle individually. Therefore, for every glucose molecule, the Krebs cycle completes two full turns.
if fermentation occurs.
Mitochondria
The Krebs cycle is an aerobic process, meaning it requires oxygen to occur.
The Krebs cycle occurs in the mitochondrial matrix of the cell.The kreb cycle takes place in the matrix of the mitochondria.
The Krebs cycle is also called the citric acid cycle.
The Krebs cycle in bacteria occurs in the cytoplasm. Unlike in eukaryotic cells, where it occurs in the mitochondria, bacterial cells do not have mitochondria, so the Krebs cycle takes place in the cytoplasm.
when oxygen is not present
If there is cell death (or death of the organism), then all intracellular chemical processes, including the Krebs cycle, would cease.
Citric acid cycle
The Calvin Cycle in Photosynthesis and The Krebs Cycle in Cellular Respiration. The Calvin Cycle occurs in chloroplasts and The Krebs Cycle occurs in the Mitochondria.
The Krebs cycle takes place in the matrix of the mitochondria.
The Krebs cycle is named after its discoverer, Sir Hans Krebs, a German-born British biochemist. Krebs first described this series of chemical reactions that occur in the mitochondria of cells in 1937.
