Answer:
The correct answer is The drug binds to the 30S small ribosomal subunit eukaryotes have 40S small sub unit.
Explanation:
Tetracycline belongs to broad spectrum antibiotic.Tetracycline is named so because it contain a derivative of four hydrocarbon rings.
Tetracycline act by inhibiting the protein synthesis process in prokatotes by binding to the small ribosomal subunit also called 30S subsunit and blocks the binding of amino acyl tRNA to the A site or attachment site of ribosome.
As eukaryotes contain 40S ribosomal subunit,it becomes difficult for tetracycline to bind with 40S ribosomal subunit of eukaryotes.
Los pulmones y el sistema respiratorio permiten la entrada del oxígeno del aire en el organismo, así como la expulsión de dióxido de carbono al espirar. La respiración es el término que se utiliza para denominar el intercambio de oxígeno procedente del entorno por el dióxido de carbono que se produce en las células.
The correct answer is: the short half-life of edrophonium makes it impractical for long-term.
Edrophonium is used for the diagnostic of myasthenia gravis. In patient with myasthenia gravis, the body produces autoantibodies which inhibit nicotinic acetylcholine receptors in the neuromuscular junction. Edrophonium, on the other hand, is acetylcholinesterase inhibitor which blocks the effect of acetylcholinesterase enzymes (AcH stays in synaptic cleft).
Substitution for the edrophonium is pyridostigmine which is also acetylcholinesterase inhibitor but with long-term maintenance.
That process is called homeostasis
