Where does glycolysis and the citric acid cycle occur in bacterial cells?

Both the citric acid cycle and glycolysis occur in the cytoplasm of bacteria. In addition, the citric acid cycle also occurs in periplasm. Like in humans, the citric acid cycle in bacteria is the first step of oxidative energy metabolism. The citric acid cycle converts pyruvate to acetyl-CoA and generates two reducing equivalents (NADPH and NADH). NADPH production, the first step of the oxidative pentose phosphate pathway,

Where does glycolysis occur in bacteria?

In most bacteria, aerobic respiration or oxidative phosphorylation is the only energy-generating process that operates. This means that these bacteria can metabolize glucose anaerobically, with a high efficiency. Glycolysis takes place in the cytoplasm and produces two energetic by-products: three molecules of adenosine triphosphate (ATP) and two of nicotinamide adenosine dinucleotide (NADH), which is a form of reduced nic

Where does the Krebs cycle occur in bacteria?

The citric acid cycle is another important process for bacteria. It produces energy and intermediates for other essential functions. Like the glycolysis pathway, the citric acid cycle occurs in the cytoplasm, where it is linked to the electron transport chains. However, this particular pathway can be found in the periplasm as well as the cytoplasm.

Where does the citric acid cycle occur in bacteria?

The citric acid cycle occurs at the inner membrane of bacteria. This organelle is the place where bacteria oxidize acetyl-CoA to carbon dioxide and water. Note that bacteria do not have a respiratory enzyme, meaning they cannot use oxygen as an electron acceptor. Thus, the citric acid cycle is used to produce energy for cell growth and division.

How does the citric acid cycle occur in bacterial cells?

The citric acid cycle, also known as the Krebs cycle or TCA cycle, is the major route for the oxidative degradation of sugars to generate energy. The citric acid cycle consists of eight chemical reactions: four reactions that create oxaloacetic acid (OAA), four reactions that convert oxaloacetic acid into acetyl-CoA, and two reactions that convert acetyl-CoA into water and carbon dioxide. The first reaction of the citric acid cycle, called the
