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)DNARNANucleusRibosomesendoplasmic riticulum (rough and smooth)Chloroplasts (only in plants and some protists)cell wall (only found in plants and fungi)Lysosomes (only found in animals)Vacuole (the large central vacuole is only found in plants)Golgi apparatusMitochondriaCentriole (only in animals ...
