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.

Explanation:

That option is referring to nutrition, which is the process by which nutrients contained in food meet the needs of cells and allow the proper development of organs. For example, certain organs such as the liver, brain, heart and kidneys, in normal conditions account for 60-70% of total energy expenditure of the organism, to which we must add the energy used in the synthesis and in the new tissue formation
