  • 2. 

    When is Insulin needed?

    • When the blood glucose concentration is high.

    • When the blood glucose concentration is low.

    • When the blood glucose concentration is normal.

    Correct Answer
    A. When the blood glucose concentration is high.
    Explanation
    Insulin is needed when the blood glucose concentration is high because insulin is a hormone that helps regulate blood sugar levels. When blood glucose levels are high, the pancreas releases insulin to signal cells to take in glucose from the bloodstream, thereby lowering blood sugar levels. Insulin also helps store excess glucose as glycogen in the liver for later use. Therefore, when blood glucose concentration is high, the body requires insulin to bring it back to normal levels and maintain overall glucose homeostasis.

    Which of the following is NOT the function of the liver?

    • Contains sodium bicarbonate(alkaline) which neutralizes the acidic material from the stomach.

    • Regulates blood glucose concentration.

    • Plays a role in carbohydrate metabolism.

    • The liver detoxifies blood from intestines.

    Correct Answer
    A. Contains sodium bicarbonate(alkaline) which neutralizes the acidic material from the stomach.
    Explanation
    The liver performs many important functions in the body, including regulating blood glucose concentration and playing a role in carbohydrate metabolism. It also detoxifies blood from the intestines. However, the liver does not contain sodium bicarbonate to neutralize acidic material from the stomach. This function is performed by the pancreas, which produces and releases bicarbonate ions into the small intestine to neutralize the acidic chyme coming from the stomach.

    Which of the following is NOT found in pancreatic juice?

    • Lipase

    • Trypsin

    • Protease

    • Chymotrypsin

    Correct Answer
    A. Protease
    Explanation
    Protease is not found in pancreatic juice. Pancreatic juice contains enzymes that aid in the digestion of proteins, fats, and carbohydrates. Lipase is an enzyme that helps break down fats, trypsin is an enzyme that breaks down proteins, and chymotrypsin is another protein-digesting enzyme. However, protease is a general term that encompasses enzymes that break down proteins, so it is not specific to pancreatic juice.

    Which of the following is false about the regulation of liver?

    • The liver detoxifies blood from intestines

    • The liver receives regulatory innervation via hormones in the blood and through the autonomic nervous system.

    • Iiver destroys old red blood cells and converts hemoglobin from these cells to bilirubin and biliverdin which are components of bile.

    • Ammonia produced by the digestion of proteins is converted to a less toxic compound by the liver.

    Correct Answer
    A. The liver receives regulatory innervation via hormones in the blood and through the autonomic nervous system.
    Explanation
    The liver receives regulatory innervation via hormones in the blood and through the autonomic nervous system. This statement is false because the liver does not receive regulatory innervation through hormones in the blood. Instead, the liver is regulated by the autonomic nervous system, which consists of sympathetic and parasympathetic nerves. These nerves control the liver's functions such as glucose metabolism, bile production, and detoxification.
