Document Summary

Cytobacteria drove oxygen phosphorylation and an electron could be taken from water. Can produce much more energy through oxygenative phosphorylation. Identify the paradox for why prokaryotes are biochemical complex don"t develop morphological complexity.

Relationship between surface area and volume as cells get larger. The larger the cell, the more oxygen-phosphorylation units required. Energy produced is proportional to the sa so not enough is produced to support the volume. Chemiosmosis using a proton gradient to produce energy. Pmf is the energy that is in a proton gradient. Relationship between chemiosmotic membranes (units) and need for genes to code for its proteins. Need to repair faster so gene encodes its own proteins. Genome size relationships between e. coli, epulopisculium and eukaryotes. Genome size from smallest to largest is: e. coli, epulopisculium, eukaryotes.
