D Correct answer
Explanation

Penicillin, one of the first and still one of the most widely used antibiotic agents, derived from the Penicillium mold.In 1928 Scottish bacteriologist Alexander Fleming first observed that colonies of the bacterium staphylococcus aureus failed to grow in those area of a culture that had been accidentally contaminated by the green mold Penicillium notatum.The greatest number of antimicrobic allergies is also reported for Penicillins

Which of the following statements is accurate in explaining why Gram negative bacteria are generally more resistant to penicillins than Gram positive bacteria?

  1. Gram negative bacteria have a thicker cell wall

  2. Gram negative bacteria have an outer hydrophilic membrane that acts as an extra barrier
  3. Gram negative bacteria can concentrate $\beta$-lactamase enzymes in the periplasmic space

  4. Gram negative bacteria produce smaller quantities of transpeptidase enzyme
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Gram negative bacteria can concentrate $\beta$-lactamase enzymes in the perplasmic space between the cell wall and the outer membrane. Some Gram positive bacteria can produce $\beta$-lactamase enzyme, but these enzymes diffuse away from the cell because there is no outer membrane to trap them . Thus, they are less effective than $\beta$-lactamases produced by Gram negative bacteria.

  3. sulfonamide

  4. penicillin
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Penicillin was discovered in 1928 by Scottish scientist Alexander Fleming. People began using it to treat infections in 1942. There are several enhanced penicillin families which are effective against additional bacteria; these include the antistaphylococcal penicillins, aminopenicillins, and the antipseudomonal penicillins. They are derived from Penicillium fungi.

The birth control pills are which kind of drug?

  1. analgesics

  2. tranquilizers

  3. sulphapyridine

  4. antifertility
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Antifertility agents are drugs that control fertility and are also called oral contraceptives. These drugs affect and are involved in the menstrual cycle and ovulation in females. Estrogen and progesterone in combined form are given as birth control pills. The antifertility substance is deemed to be active in females when it prevents fertilization, prevent ovulation, implantation, and destroys the zygote or causes abortion.
