23 Οκτ 2020 · During aerobic respiration, the electron transport chain, and most of the chemical reactions of respiration, occur in the mitochondria. The mitochondria’s system of membranes makes the process much more efficient by concentrating the chemical reactants of respiration together in one small space.
31 Οκτ 2023 · Both methods are called anaerobic cellular respiration, where organisms convert energy for their use in the absence of oxygen. Certain prokaryotes, including some species of bacteria and archaea, use anaerobic respiration.
28 Μαΐ 2024 · In the fluid part of the cytoplasm, anaerobic respiration (both glycolysis and fermentation) takes place, while the majority of the energy production in aerobic respiration takes place in the mitochondria.
30 Ιουλ 2022 · Most ATP from glucose is generated in the electron transport chain. It is the only part of cellular respiration that directly consumes oxygen; however, in some prokaryotes, this is an anaerobic pathway. In eukaryotes, this pathway takes place in the inner mitochondrial membrane. In prokaryotes it occurs in the plasma membrane.
Anaerobic cellular respiration takes place only in the cell cytoplasm and does not involve mitochondria. Anaerobic cellular respiration provides less ATP (so less energy) than aerobic cellular respiration, but more quickly. Uses of anaerobic cellular respiration (fermentation) in yeast.
In aerobic respiration in mitochondria, the passage of electrons from one molecule of NADH generates enough proton motive force to make three ATP molecules by oxidative phosphorylation, whereas the passage of electrons from one molecule of FADH 2 generates enough proton motive force to make only two ATP molecules.
23 Ιαν 2024 · It suggests a symbiotic relationship between an anaerobic or facultatively anaerobic eukaryote and a hydrogen-producing bacterium (the future mitochondrion). The theory emphasizes the role of hydrogen and energy transfer in the establishment of the symbiotic relationship .
