C. electron transport and chemiosmosis
Chemiosmosis<span> involves movement of </span>ions<span> across a </span>semipermeable membrane<span>, down their </span>electrochemical gradient<span>. More specifically, it relates to the generation of </span>adenosine triphosphate<span> (ATP) by the movement of </span>hydrogen<span> ions across a </span>membrane<span> during </span>cellular during respiration<span> </span><span>.</span>Hydrogen ions, or protons<span>, will </span>diffuse<span> from an area of high proton concentration to an area of lower proton concentration, and an </span>electrochemical concentration gradient<span> of protons across a membrane can be harnessed to make ATP. This process is related to </span>osmosis<span>, the diffusion of </span>water<span> across a membrane, which is why it is called "chemiosmosis".</span>
