Where does the citric acid cycle take place in a eukaryotic cell?
The citric acid cycle is the process by which acetyl-CoA, the building block for fatty acids, and oxaloacetic acid, the two-carbon end product of glycolysis, combine with six molecules of NAD+ to produce two molecules of NADH, two molecules of ATP, and two molecules of carbon dioxide. This multi-step process occurs in the mitochondrial matrix, the membrane-bound compartment inside the cell containing the mitochondria.
Where does the citric acid cycle take place in a human cell?
The citric acid cycle is located in the mitochondrial matrix of human cells. This organelle is responsible for energy production and for the synthesis of important molecules like proteins and lipids.
Where does the citric acid cycle take place in an animal?
The citric acid cycle takes place in the mitochondria of most animal cells. The exception is the embryonic stage of development in humans and other mammals, as well as the early development of some plants and fungi. In animal cells, the citric acid cycle takes place in the matrix of the mitochondria. The enzymes involved are located within these organelles. The citric acid cycle produces energy in the form of Adenosine triphosphate (ATP) for use by the cell.
What is the location of the citric acid cycle in a eukaryotic cell?
As you can see in the figure, the citric acid cycle occurs in the mitochondria of the cell. This is the powerhouse of the cell, the place where the chemical energy created from food is stored and used to power the cell’s activities. It is the point at which oxygen is added to the carbon skeletons created in the TCA cycle, which allows for a further increase in the amount of energy.
Where does the cit
The citric acid cycle occurs in the mitochondrial matrix of eukaryotic cells. Mitochondria are subcellular structures that use aerobic respiration to carry out biochemical reactions. In the citric acid cycle, acetyl coenzyme A, which is formed during glycolysis, is the first metabolite to be oxidized by the Krebs cycle. This reaction is catalyzed by a series of enzymes known as the tricarboxylic acid (TCA) cycle enzymes
