Document Summary
Bacteria and archaea are not related at all (don"t use the term prokaryotes much any more) More similar to eukaryotes than to bacteria. However, we can talk about prokaryotic cell structure. No nucleus, no organelles, and lack morphological complexity. They been around for 4 billion years. Enzymes and nd biochemical pathways (make unique molecules) Lead to development of bacteria that undergo aerobic respiration. Make lots of energy (huge energy advantage) Eukaryotes can make a lot more energy than bacteria. Potential energy associated with the charge difference (voltage) across the membrane and concentration difference (in this case, proton gradient) across the membrane. A proton has both charge and concentration across a membrane. A chemiosmosis unit (unit of oxidative phosphorylation) has: Etc, atp-synthase (everything need to produce atp) Requires a membrane for it to function. Need energy to support the increase in volume. Units of o. p. requires membrane space to produce atp.
