Where does the citric acid cycle occur in eukaryotes?
The citric acid cycle occurs in the matrix of the mitochondria and is the final common pathway for the oxidation of carbohydrates, fatty acids, and amino acids in aerobic respiration. This means that the citric acid cycle produces energy under aerobic conditions by producing Adenosine Triphosphate (ATP). The citric acid cycle consists of eight chemical reactions that occur in the mitochondrial matrix. These eight chemical reactions use a series of eight enzymes which are responsible for the conversion of each metabolite in
What is the citric acid cycle in humans?
Ordinarily, the citric acid cycle occurs in the mitochondria of eukayotes to produce energy. However, in humans, this function is performed by the liver because the mitochondria are unable to use oxygen as a final electron acceptor (this is a result of a mutation in the mitochondrial genome).
Where does the citric acid cycle occur in mitochondria?
The citric acid cycle occurs in the matrix of the mitochondria, which is the inner compartment of the cell. The citric acid cycle is a series of chemical reactions that take place within the mitochondria using the energy stored in the form of a high-energy phosphate bond. The results of the citric acid cycle are reduced nicotinamide adenine dinucleotide (NADH) and flavin adenine dinucleotide (FAD), which are the two molecules
Where is the citric acid cycle in humans?
In humans, the citric acid cycle can be found in the mitochondrial matrix and intermembrane space, with the first two reactions taking place in the matrix. The cycle is completed when the two-carbon product, NADH, is transported to the mitochondrial respiratory chain to produce the energy needed for cellular processes.
Where does the citric acid cycle occur in humans?
Humans have a single copy of the mitochondrial genome so the citric acid cycle occurs in this organelle. The citric acid cycle is responsible for generating ATP in the presence of oxygen. The cycle begins with the oxidation of acetyl-CoA to form citrate, which is the first reaction of the cycle. Citrate is then converted to oxaloacetate by the enzyme citrate synthase. One of the four fumaric acid molecules produced during the reaction is recycled back to malic
