Answer:

D. Allosteric activator

Explanation:

In an enzyme, the allosteric site is a site/motif different from the active site, (i.e., the site with catalytic activity) which is able to interact with regulatory effector molecules in order to activate or inhibit enzymatic activity by influencing the tridimensional (3D) structure of the enzyme. An allosteric activator is an effector molecule with the ability to bind to a specific enzyme at a different site than the active site, thereby modifying the shape of the enzyme and increasing the affinity of this enzyme for its substrate. Moreover, Adenosine monophosphate (AMP) is a nucleotide composed of a phosphate group, a sugar ribose, and an Adenine (A) base. This effector molecule (AMP) has shown to allosterically stimulate diverse enzymes in physiological conditions (e.g., AMP-activated protein kinase).

Which hypothalamic hormone would the nurse identify as helping treat postpartum uterine atony and hemorrhage?
klio [65]

The hypothalamic hormone that the nurse would identify as helping treat postpartum uterine atony and hemorrhage is oxytocin.

<h3>What is oxytocin?</h3>

Oxytocin is a neuropeptide that is produced in the hypothalamus and is responsible for modulating the central nervous system for patterns of sexual behavior and that is secreted after distension of the uterine cervix during childbirth.

When released into the blood, it travels a path to where its receptors are to generate its functions such as the contraction of the muscle of the uterus during delivery, being responsible for the contractions. It will also generate the milk ejection reflex in the breasts, helping during lactation.

Therefore, we can confirm that the hypothalamic hormone that the nurse would identify as helping treat postpartum uterine atony and hemorrhage is oxytocin.
