Answer 1

1. The correct answer is e) Troponin. Troponin is a complex of three regulatory proteins (troponin C, troponin I, and troponin T) that are integral to muscle contraction in skeletal muscles. 2. The correct answer is a) T-tubules. T-tubules (transverse tubules) are invaginations of the sarcolemma that allow the action potential to spread to the deeper parts of the skeletal muscle cell. 3. The correct answer is d) Ergometer. An ergometer is an exercise device that allows the control and measurement of exercise intensity, such as a treadmill or stationary bicycle. 4. The correct answer is b) Serum. Serum is the remaining fluid after whole blood has been allowed to clot without adding an anticoagulant, and the clot has been removed. 5. The correct answer is b) ATP-creatine phosphate. The ATP-creatine phosphate system is the primary energy system used during the first few seconds of exercise. 6. The correct answer is c) It is located in the heart muscle and allows the stimulus to quickly distribute from one muscle fiber to another. Gap junctions are specialized intercellular connections that allow the rapid transmission of electrical signals between cardiac muscle cells. 7. The correct answer is a) EPO is produced in the kidneys and stimulates the production of red blood cells. Erythropoietin (EPO) is a hormone produced by the kidneys that stimulates the production of red blood cells. 8. The correct answer is a) Actin and myosin. Actin and myosin are the two main contractile proteins involved in muscle contraction in skeletal muscles. 9. The correct answer is c) AB group. An individual who carries A agglutinogen in the erythrocyte membrane and B agglutinogen (Anti-B) in the plasma has blood type AB.
