Ph in mitochondria
Webb25 okt. 2024 · Mitochondria have two membranes, outer and inner that create two isolated compartments (): the intermembrane space and the mitochondrial matrix ().Though the outer membrane of mitochondria possesses ion channels (), it is less selective and acts as a molecular sieve.In contrast, the inner membrane is highly ion-selective (43–47).The … WebbThese measurements established that Δp ranges from 180 to 220 mV depending on the metabolic state of the mitochondria, with ΔΨ m ranging from 150 to 180 mV and ΔpH m …
