Document Summary
When we talk about oxygenic photosynthesis or respiration, there"s nothing eukaryotic about it. So there are bacteria (prokaryotic cells) that look like the chloroplast, or the mitochondria (undergo aerobic respiration). You want to transfer the energy of glucose into atp (cellular currency). There"s no carbon left at the stage of et. The point of etc is the get the remainder of atp that we can, from nadh and fadh2. We want to oxidize those molecules so we can utilize all of the energy that was once in the c-h bonds of glucose into atp. Like photosynthesis, there are giant complexes embedded in the inner mitochondrial membrane. The potential energy in electrons as they move down the etc and through the complexes is used to pump protons from the mitochondrial membrane out into the intermembrane space. These protons get pumped back into the mitochondrial matrix by atp synthase.
