Question: How is the correction of an erroneous amino acid incorporated in the process of translation in the ribosome carried out? 
 Options:  <0> There is no possibility of elimination of an amino acid in the synthesis of proteins. <1> Through the aminoacyl peptidase activity of the ribosome. <2> A dipeptidase removes the wrong amino acid, before proceeding with the synthesis. <3> Thanks to the fact that amino acids are energy-rich molecules. <4> There is a post-translational sequence review system.
pharmacology

Question: The state characterized by a total absence of consciousness, muscle laxity, absence of response to painful stimuli and posterior lacunar amnesia, is called:

psychology

Question: When administering oxygen therapy to a patient admitted to the emergency room due to exacerbated COPD, you should take into account that: 
 Options:  <0> The flow of oxygen must be high, since respiratory failure is accompanied by hypoxia. <1> The concentration of oxygen is conditioned by the patient's clinical situation. <2> The concentration of oxygen must be equal to the atmospheric concentration, since the patient presents hypercapnia. <3> The flow should be low, since hypoxia is the only stimulus to breathe. <4> The flow must be adjusted to achieve a PO2 greater than 90 mmHg.
