A nurse assisting a nursing student with medications asks the student to describe how penicillins (PCNs) work to treat bacterial
Mnenie [13.5K]

Penicillins disrupts bacterial cell wall synthesis.

<h3>How does penicillin affect bacterial cell walls?</h3>
  • Penicillin kills bacteria by inhibiting the proteins which cross-link peptidoglycans in the cell wall .
  • When a bacterium divides in the presence of penicillin, it cannot fill in the “holes” left in its cell wall.
  • β-Lactam antibiotics, including penicillins, cephalosporins, monobactams, and carbapenems, are distinguished by a lactam ring in their molecular structure and act by inhibiting the synthesis of the peptidoglycan layer of bacterial cell walls.
  • Penicillins work by bursting the cell wall of bacteria. Drugs in the penicillin class work by indirectly bursting bacterial cell walls.
  • They do this by acting directly on peptidoglycans, which play an essential structural role in bacterial cells.

The moon causes the earths Rotation to speed up / slow down which ?
My name is Ann [436]

Answer: slow down

Explanation:As Earth rotates, the Moon's gravity causes the oceans to seem to rise and fall. (The Sun also does this, but not as much.) There is a little bit of friction between the tides and the turning Earth, causing the rotation to slow down just a little. As Earth slows, it lets the Moon creep away.

Solnce55 [7]

Answer:

In Late 1600s Anton von Leeuwenhoek develops a more powerful microscope that allows him to see living cells like bacteria.

In Early 1800s Matthias Schleiden and Theodor Schwann conclude that all living organisms are made of cells, and that cells can be produced from other cells.

Given the following events involved in the regulation of blood volume, which one of the following answers best represents the or
Ad libitum [116K]

Answer:

The correct answer will be-

1. decrease in blood volume

2. secretion of renin from juxtaglomerular apparatus

3. production of angiotensin II

4.  secretion of aldosterone

5. sodium reabsorbed from distal tubules and collecting ducts

Explanation:

The RAAS pathway or Renin-angiotensin II-aldosterone pathway gets activated in the human body to maintain the osmolarity and blood volume.

When the receptors in the blood sense the low volume of water in the body sends signals to the brain which activates the secretion of the renin from the juxtaglomerular cells. Renin helps converts the inactive angiotensin to angiotensin I and II which help reabsorption of sodium ions. This activates the production of aldosterone which increases the reabsorption of the sodium ions into distal and collecting ducts.
