Answer:
Option (A).
Explanation:
Muscle contraction may be defined as the physiological process of the activation of tension generating sites that occur within the muscle fibers. Actin, myosin, troponin and other proteins are important for muscle contraction.
The calcium ion is important for the muscle contraction. The binding of calcium with troponin causes the movement of tropomyosin out of the grooves between the actin molecules during muscle contraction.
Thus, the correct answer is option (A).

zoology; study of animals
botany; study of plants
microbiology; study of very tiny living beings

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.
