Where does the Krebs cycle occur in eukaryotic cells?
The Krebs cycle occurs inside the mitochondria of most eukaryotic cells. This is where the cell obtains the chemical energy it needs for all of its processes. However, the Krebs cycle can occur in the cytosol as well, outside of the mitochondria. These are known as ‘cytoplasmic Krebs cycles,’ and they are thought to help maintain the energetic balance in the cell.
Where does the Krebs cycle occur in plant cells?
The Krebs cycle occurs in the cytoplasm of plant cells. This allows the plant cell to transport nutrients, such as sugars, to the different parts of the cell. The Krebs cycle is also responsible for generating the energy required for the plant cell to function and grow. Since plants do not have a mitochondria (the site of oxidative phosphorylation in animal cells), they use a different way to generate energy from the oxidation of organic compounds, called glycolysis.
Where does the Krebs cycle occur in a plant cell?
The Krebs cycle occurs in the matrix of plant cells, the cytosol. The cytosol is the liquid inside plant cells that contains enzymes, metabolites, and other substances needed for cell processes. Plant cells also contain a plastid, a type of cellular organelle found in all plant cells, except for algae and fungi. The chloroplasts carry out the photosynthesis process that converts sunlight and carbon dioxide into chemical energy.
Where does the Krebs cycle occur in cells?
It's not in the mitochondria, which is where most aerobic respiration happens. The Krebs cycle takes place in the cytosol (the fluid inside a cell), which is where the cell nucleus is located. This means that the Krebs cycle generates products that can be transported to the nucleus to fuel the cell’s other energy-consuming processes. This also means that any damage to the mitochondrial membranes would stop the Krebs cycle from happening, so the cell has to keep its membranes
Where does the Krebs cycle occur in human cells?
In humans, the body uses the process of glycolysis to create glucose (or sugar), and the citric acid cycle to create energy in the form of ATP. Both the Krebs cycle and the TCA cycle occur in the mitochondria of most cells; however, specialized cells such as brain cells, red blood cells, and cells that produce sperm use only the TCA cycle.
