Where does the citric acid cycle take place in eukaryotic cells?
The citric acid cycle is present in all living organisms and is responsible for the breakdown of the three macronutrients, carbohydrates, proteins, and fats. In eukaryotic cells, the citric acid cycle begins with the conversion of acetyl-CoA into oxaloacetate. It continues by passing through a series of reactions that create two byproducts: NADH and FADH2. These two coenzymes are essential for transferring energy to the electron transport chain where the
Where does the citric acid cycle take place in fungi?
In fungi, the TCA cycle takes place in the cytosol. This location allows fungus cells to use the citric acid cycle for generating energy, as there are no organelles in which the TCA cycle could take place within the fungi. The TCA cycle in fungi is also important for providing intermediates for the synthesis of a variety of essential compounds including amino acids, lipids, NADPH, and other compounds.
Where does the citric acid cycle take place in plants?
In plants, the citric acid cycle occurs in the cytosol of plastids, which are organelles that contain chloroplasts. Chloroplasts are the site of photosynthesis, the process plants use to convert sunlight (in the form of chemical energy) into food, such as starch. One carbon skeletons created during photosynthesis are used by plastids to produce NADPH and ATP, and the remaining carbon skeletons are used in the citric acid cycle. TCA cycle
Where does the citric acid cycle take place in animals?
The citric acid cycle takes place in the cytoplasm of animal cells. This means that the cycle takes place inside the cell’s cytoplasm, where the cell’s nucleus, ribosomes and other organelles are located. The citric acid cycle is usually a multi-step reaction in which a series of chemical reactions are carried out. In the first step, acetyl-CoA reacts with oxaloacetic acid to produce citric acid.
Where does the citric acid cycle take place in humans?
Humans have two citric acid cycles. One is in the liver and the other is in the muscles. These cycles are called the mitochondrial and cytosolic cycles, respectively. The primary function of the citric acid cycle in the liver is to produce energy and to remove waste products, such as carbon dioxide. The primary function of the cytosolic citric acid cycle in the muscles is to produce energy. The citric acid cycle in both the liver and the muscles is only a part of the
