where does krebs take place in bacteria
Citric Acid Cycle (Krebs Cycle) Definition. The citric acid cycle, also known as the Krebs cycle or tricarboxylic acid (TCA) cycle, is a series of chemical reactions in the cell that breaks down food molecules into carbon dioxide, water, and energy. In plants and animals (eukaryotes), these reactions take place in the matrix of the mitochondria of the cell as part of cellular respiration. Many bacteria perform the citric acid cycle too, though they do not have mitochondria so the reactions take place in the cytoplasm of bacterial cells. In bacteria (prokaryotes), the plasma membrane of the cell is used to provide the proton gradient to produce ATP.
