Answer:
The correct answer is - false.
Explanation:
Penicillin-binding protein 2a or PBPs are protein produced by bacteria that binds with the β-lactam antibiotics such as penicillin. They play role in the cell wall synthesis of bacteria by producing peptidoglycan by catalyzing the reaction.
β-Lactam antibiotics bind with the PBPs and cause the disruption to peptidoglycan cross-linking in the biosynthesis of the cell wall and ultimately lysis of bacteria takes place and cell death.

Infant suckling
<span>Infant suckling is the stimulus that is needed
for continued and sustained production of breast milk. When an infant suckles, stimuli
