According to the endosymbiotic theory of the origin of both chloroplasts and mitochondria, the ancestors of these two organelles were free-living prokaryotic cells.

yaroslaw [1]

Answer and Explanation:

The mechanism of action of statins begins with the inhibition of a protein called HMG-CoA reductase, allowing its substrate to accumulate in the body and promote cholesterol reduction. At that moment, a transporter called OATP (Organic Anion Transporting Polypeptides) takes statins to the epatic tissue where they will be transformed and metabolized until they are eliminated through bile. This elimination is influenced by the P-glycoprotein, which is the main cause of the efflix presented by the bili. This process can get help from other molecules like some protease inhibitors, digoxin and cyclosporine.
