Where does the citric acid cycle occur in eukaryotic cells?
The citric acid cycle occurs in the mitochondrial matrix of eukaryotic cells.
Where does the citric acid cycle occur in plant cells?
Plant cells contain chloroplasts, organelles responsible for photosynthesis and energy production, which use the citric acid cycle as a source of carbon and energy. The citric acid cycle is necessary to produce energy and carbon dioxide, which are the two end products of photosynthesis. Carbohydrates are initially broken down into a two-carbon sugar called glucose. A subsequent reaction produces two additional carbon dioxide molecules and four high-energy compounds called “ATPs.”
Where does the citric acid cycle occur in red blood cells?
In the red blood cells, the citric acid cycle occurs within the mitochondria, as these organelles are the main site of aerobic respiration. Blood cells do not have a nucleus, thus the citric acid cycle also produces energy for the cell. Furthermore, the citric acid cycle is the primary source of energy for the brain. This means that the citric acid cycle plays a vital role in the function of the brain.
Where does the citric acid cycle occur in neurons?
The citric acid cycle occurs in the mitochondria of neurons. This allows neurons to function efficiently and keep up with their high energy demands. However, people who have defective citric acid cycle enzymes often develop severe neurological problems such as epilepsy, intellectual disabilities, and autism. This is because of the importance of energy production for the correct function of neurons.
Where does the citric acid cycle occur in humans?
The citric acid cycle occurs in the cytosol of most eukaroytic cells. The nucleus, however, does not use the citric acid cycle directly for energy production. Instead, the citric acid cycle produces NADPH, which is then used by the nucleus to produce the building blocks of DNA and RNA.
