The Vital Force

So, how is oxygen involved in bioenergetics? Perhaps remarkably, the modern view of bioenergetics only recently emerged in the closing decades of the 20th century. 

As related in this volume, the chemiosmotic hypothesis of Peter Mitchell roiled the field of bioenergetics and led to the nearly two-decade “oxphos wars.” In the end, the chemiosmotic hypothesis was triumphant, and bioenergetics became the study of building and harnessing trans-membrane ion gradients. 

In this context, oxygen takes its place as a terminal electron acceptor, which by facilitating electron flow through the electron transport chain, helps to build the trans-membrane proton gradient. There… show more.
