Question

Many of the redox centers that comprise the electron transport system (ETS) are integral components of larger protein complexes, whereas others, such as ________, freely diffuse within the membrane as they ferry electrons between other ETS components.

Answer 1

Electron Transport Chain

Explanation:

• Quinones is right answer

• The Quinones are network site,that the lipid -soluble carriers that adjusted electron and proton between The macromolecular complex which is embedded in the membrane layer and large
• The Bacteria used related quinones and ubiquinone such as menaquinone(Vitamin K2)
• The protons are act as pumped from the oxygen decreases to form water and the mitochondrial matrix to the middle membrane space
