WebWhen phosphorylation is partially uncoupled from electron flow, one would expect a decrease in the proton gradient across the inner mitochondrial membrane and, hence, impaired ATP synthesis. In an attempt to compensate for this delect in energy capture, metabolism and electron flow to oxygen is increased.

WebJun 5, 2024 · Cyanide poisoning is an example of histotoxic hypoxia resulting from tissue poisoning by C N − ions. Unlike other forms of hypoxia where the concentration of oxygen is less in tissues, in cyanide poisoning, the concentration of oxygen is perfectly normal in both the extra- and intracellular fluid. WebMay 18, 2024 · Figure 8.6. 1: The electron transport chain is a series of electron transporters embedded in the inner mitochondrial membrane that shuttles electrons from NADH and FADH 2 to molecular oxygen. In the process, protons are pumped from the mitochondrial matrix to the intermembrane space, and oxygen is reduced to form water.
