Where do reactions of the citric acid cycle occur in eukaryotic cells?

Most of the reactions of the citric acid cycle occur in the mitochondria matrix. The mitochondrial matrix is an area inside mitochondria where enzymes involved in oxidative phosphorylation reside. This is where the citric acid cycle takes place. However, there are exceptions to this. One is the isocitrate dehydrogenase reaction which takes place in the cytosol and, in some cases, the peroxisomes. The final step of the citric acid cycle, the formation of α-

Where do citric acid cycle reactions occur in plant cells?

The citric acid cycle occurs in plant cells within the mitochondria the energy-generating organelles in plant cells. This means that plants don’t have to get their energy from food the way animals do. Plant cells use solar energy to drive the reactions of the citric acid cycle.

Where do reactions of the citric acid cycle occur in mammalian cells?

Large portions of the citric acid cycle occur in the endosome, the small membrane-bound internal compartments of the cell. These organelles contain many of the enzymes necessary for the breakdown of food to provide necessary nutrients for the cell. The endosome also contains a small percentage of the citric acid cycle enzymes. This allows the cell to break down food that has been partially or completely broken down in the lysosome, allowing the cell to use the nutrients from the food

Where do reactions of the citric acid cycle occur in

The citric acid cycle takes place in the mitochondria of eukayotic cells. The citric acid cycle begins with the complete oxidation of acetyl-CoA to CO2 by a process called the tricarboxylic acid cycle (TCA cycle), so the name of the cycle makes sense. During the TCA cycle, NAD+ is reduced to NADH and CO2 is produced. This process takes place in the three reactions of the TCA cycle that occur in the

Where do citric acid cycle reactions occur in mitochondria?

The citric acid cycle is a step-by-step chemical reaction that takes place in the mitochondria of eukaryotic cells, including humans. The citric acid cycle’s main purpose is to produce usable energy for the cell, in the form of adenosine triphosphate (ATP). The citric acid cycle’s other important role is in the production of the 20 amino acids that make up the building blocks of proteins.
