Oxidative phosphorylation is the step of cellular respiration that  produces the most ATP. The process that uses energy stored in a  hydrogen ion gradient across a membrane â¦ to drive ATP synthase is  chemiosmosis.
In eukaryotic cell, DNA is found at the nucleus, which is bounded by a double membrane. (the word eukaryotic is from the Greek eu, true, and karyon, kernel, here referring to the nucleus). Eukaryotic cells are much larger than prokaryotic cells; size is general aspect of cell structure that relates to function.
4 Eukaryotic Chromosomes Eukaryotic species contain one or more sets of chromosomes; each set is composed of several different linear chromosomes. The total amount of DNA in eukaryotic species is typically greater than that in bacterial cells.
