Answer:
Amoxicillin inhibits an enzyme required to build cell walls in bacteria.
Since humans have cell membranes, they are unaffected by amoxicillin.
Explanation:
Antibiotics are specifically designed to target bacterial cells, therefore, they don't kill human cells.
Amoxicillin, a type of penicillin, inhibits the biosynthesis of bacterial cell wall. The bacterial cell wall contains peptidoglycan that constitutes almost 95% of the cell wall in some Gram positive bacteria and as little as 5-10% of the cell wall in Gram negative bacteria. Amoxicillin inhibits the cross linkage between the linear peptidoglycan polymer chains that make up a major component of the cell walls of both Gram positive and Gram negative bacteria.
When a nerve impulse arrives at the neuromuscular junction, hundreds of small vesicles (pouches) containing the neurotransmitter acetylcholine are released from the axon tip into the synapse.
A synapse is formed when the tip of each axon comes into contact with a muscle fiber. A neuromuscular junction is a type of synapse that connects a motor neuron axon to a muscle fiber.
The musculature of vertebrates is often classified into three categories based on its microscopic structure: striated, cardiac, and smooth muscle. The involuntary, or autonomic, nervous system controls smooth and cardiac muscle.
