Answer:

Different enantiomers may have different or opposite physiological effects.

Explanation:

Enantiomers are organic molecules that are so named because of their shape, because for each enantiomer there is an identical but inverted shape, as if it were in front of a mirror. In other words, enantiomers are a type of isomer. Enantiomers may be the basis of therapeutic substances, since amino acids and sugars are enantiomers, and as these substances are enantiomers of each other, in different cases they have chemical similarities that allow them to be the basis of these substances. However, it is important that drugs consist of only one enantiomeric form rather than a mixture of enantiomers because different enantiomers may have different or opposite physiological effects.

Answer:

The lead whose positive electrode is placed on the left leg is II or DII (option C).

Explanation:

The electrocardiogram or EKG is a method of recording the electrical activity of the heart, useful for the diagnosis of diseases related to rhythm and heart rate. The 12-lead EKG is commonly used.

The electrode located on the left leg corresponds to the positive pole of the II or D-II lead, a bipolar peripheral lead whose negative pole is on the right arm.  The electrode on the left leg is also the positive pole of the D-III lead, which goes to the left arm, and of the monopolar AVF lead.

The other options are not possible because:

  • <em>AVR and AVL are monopolar leads located in the right and left arms, respectively.</em>
  • <em>I or D-I corresponds to the bipolar lead whose poles are located between both upper extremities.</em>
