The membrane that prokaryotes and eukaryotes share is a plasma membrane. They both can synthesize ATP from the plasma membrane but eukaryotes can also synthesize ATP from mitochondria except for prokaryotes because they don’t contain mitochondria. The structure of the plasma membrane and the mitochondria is essential in enabling ATP synthesis and energy to metabolize. Another structure that is important is the proton gradient and how chemiosmosis drives ATP synthesis that occurs in the mitochondria. The importance of a plasma membrane in prokaryotes and eukaryotes, the membrane is a selective barrier which means that it only allows certain molecules enter and exit such as nutrients, oxygen, and wastes to serve the cell. The plasma membrane has hydrophilic and hydrophobic regions and also made up of phospholipids. On the hydrophobic region of the membrane some integral proteins penetrate this region. Integral proteins serve as many functions such as, intercellular joining, allowing enzymatic activity, cell-cell recognition, signal transduction and finally transporting. The main functi...
