    Penicillin is known to cause hyperkalemia, which is an elevated level of potassium in the blood. This can occur due to the effect of penicillin on the kidneys, where it can impair the excretion of potassium. As a result, potassium levels can build up in the body, leading to hyperkalemia. It is important to monitor potassium levels in patients receiving penicillin therapy, especially those with underlying kidney disease or other risk factors for hyperkalemia.

    Which of the following is NOT a drug exhibiting zero-order elimination kinetics?

    • A.

      Ethanol

    • B.

      Aspirin

    • C.

      Morphine

    • D.

      Phentoin

    Correct Answer
    C. Morphine
    Explanation
    Morphine is not a drug exhibiting zero-order elimination kinetics because it follows first-order elimination kinetics. In zero-order elimination, a constant amount of the drug is eliminated per unit of time, regardless of the drug concentration. However, in first-order elimination, a constant fraction of the drug is eliminated per unit of time, meaning that the elimination rate decreases as the drug concentration decreases. Therefore, morphine does not exhibit zero-order elimination kinetics.

    ‎106 mg of compound A (dissolved in 100 ml ethanol) in a 1 cm long cell has a lambda max 295 nm and absorbance is 0.28. then the value of A1%1 cm is...?

    • A.

      2.64

    • B.

      264

    • C.

      190

    • D.

      640

    Correct Answer
    A. 2.64
    Explanation
    The value of A1%1 cm is a measure of the absorbance of a 1% solution of the compound in a 1 cm long cell. In this case, the absorbance of the compound A at its lambda max of 295 nm is given as 0.28. Therefore, the value of A1%1 cm can be calculated by multiplying the absorbance by 100, since 1% is equivalent to 100 times the concentration. Thus, A1%1 cm = 0.28 * 100 = 28. Dividing this value by 10, since the cell length is 1 cm, gives us the final answer of 2.64.

    • D.

      PLP

    Correct Answer
    A. CDP
    Explanation
    CDP (cytidine diphosphate) is the correct answer because it is a coenzyme that is required in the synthesis of phospholipids. Phospholipids are essential components of cell membranes and play a crucial role in maintaining the integrity and function of cells. CDP is involved in the transfer of phosphatidic acid to other molecules, leading to the formation of various phospholipids. Therefore, CDP is necessary for the synthesis of phospholipids, making it the correct choice among the given options.

      IAA

    • B.

      GA3

    • C.

      Zeatin

    • D.

      ABA

    Correct Answer
    A. IAA
    Explanation
    IAA, also known as Indole-3-acetic acid, is a plant hormone that promotes cell elongation and growth in shoots. However, it inhibits root growth. This is because IAA is primarily synthesized in the apical meristem (the tip of the plant), and it moves downwards towards the roots. In the roots, IAA inhibits cell division and elongation, leading to a decrease in root growth. Therefore, IAA acts as a negative regulator of root growth in plants.
