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.
There are simply too many things that are found in a eukaryotic cell, but the basic structures and molecules are: Plasma membrane (or phospholipid bilayer) Proteins (integral, enzymes, hormones, etc) DNA; RNA; Nucleus; Ribosomes; endoplasmic riticulum (rough and smooth) Chloroplasts (only in plants and some protists) cell wall (only found in plants and fungi)
