Hader Department of Botany, University of Marburg D-J550 Marburg, Lahnberge, West-Germany SUMMARY: Light-induced reactions in microorganisms may be regarded as being composed of 網頁Mitochondria are able to encode and decode Ca²⁺ signals because the respiratory chain generates an electrochemical gradient for protons across the inner mitochondrial …
網頁For instance, Dibrov et al 12 showed that Ag + ions induced dissipation of pH gradient on membrane of inside-out membrane vesicles of Vibrio cholerae. Authors suggested that H + leakage is the main mechanism behind the bactericidal action of Ag + ions in V. cholerae , and assumed that it occurs due to the unspecific, Ag + -induced modification of proteins … Peter D. Mitchell proposed the chemiosmotic hypothesis in 1961. In brief, the hypothesis was that most adenosine triphosphate (ATP) synthesis in respiring cells comes from the electrochemical gradient across the inner membranes of mitochondria by using the energy of NADH and FADH2 … 查看更多內容 Chemiosmosis is the movement of ions across a semipermeable membrane bound structure, down their electrochemical gradient. An important example is the formation of adenosine triphosphate (ATP) by the … 查看更多內容 The complete breakdown of glucose releasing its energy is called cellular respiration. The last steps of this process occur in mitochondria. The reduced molecules 查看更多內容 Bacteria and archaea also can use chemiosmosis to generate ATP. Cyanobacteria, green sulfur bacteria, and purple bacteria synthesize … 查看更多內容 Thermal cycling model A stepwise model for the emergence of chemiosmosis, a key element in the origin of life on earth, proposes that primordial organisms used thermal cycling as an energy source (thermosynthesis), functioning … 查看更多內容 The movement of ions across the membrane depends on a combination of two factors: 1. Diffusion force caused by a concentration gradient - all particles tend to diffuse from higher concentration to lower. 2. Electrostatic force caused … 查看更多內容 The light reactions of photosynthesis generate ATP by the action of chemiosmosis. The photons in sunlight are received by the antenna complex of Photosystem II, which excites electrons to a higher energy level. These electrons travel down an 查看更多內容 • Cellular respiration • Citric acid cycle • Electrochemical gradient 查看更多內容

網頁2013年9月26日 · This is fulfilled by the transmembrane proton gradient (ΔpH) across the membrane. In neutrophiles and acidophiles, proton concentration inside the cell is less and Mitchell’s model of chemiosmotic theories (i.e., generation of ΔpH and flow of protons from higher concentration to lower concentration) can satisfactorily explain ATP generation. sublocade policy and procedure網頁Study Chapter 10 flashcards.
