Julie was diagnosed with an aggressive tumor of the thyroid. Surgery was performed to remove the thyroid. However, post-operativ
FinnZ [79.3K]

Answer:

c. accidental removal of the parathyroid glands during surgery

Explanation:

Parathyroid gland is found closely situated at the back of the thyroid gland in the human neck region. Regulation of serum calcium levels in the body is a major function of the parathyroid gland through the secretion of a hormone called parathyroid hormone or parathormone.

During the surgery conducted to remove the thyroid gland, it is very likely that the parathyroid glands were accidentally damaged or removed. This most likely led to the non--secretion of parathormone, which is responsible for secretion of calcium in the body, when calcium levels drop.

Which amino acids are the primary nitrogen donors for biosynthetic reactions in the cell?
prohojiy [21]
Glutamine and glutamate are the primary nitrogen donors for biosynthetic reactions in the cell.  Glutamine is an α-amino acid that is used in the biosynthesis of proteins. Its side chain is similar to that of glutamic acid, except the carboxylic acid group is replaced by an amide. It is classified as a charge-neutral, polar amino acid. It is non-essential and conditionally essential in humans, meaning the body can usually synthesize sufficient amounts of it, but in some instances of stress, the body's demand for glutamine increases, and glutamine must be obtained from the diet. Glutamate is generally acknowledged to be the most important transmitter for normal brain function. Nearly all excitatory neurons in the central nervous system<span> are glutamatergic, and it is estimated that over half of all brain synapses release this agent. Glutamate plays an especially important role in clinical neurology because elevated concentrations of extracellular glutamate, released as a result of neural injury, are toxic to neurons</span>

Effector molecule binding changes the behavior of enzymes by altering the equilibrium between the tense (T) state and the relaxe
9966 [12]

Answer:

Explanation:

<h2>Homotropic effector-</h2>
  • \text{accounts for the sigmoidal nature of a velocity versus substrate concentration curve}
  • \text{An enzyme's substrate.}
<h2>Both -</h2>
  • \text{Works by altering T/R ratio.}

The phrase  \text{"accounts for the sigmoidal nature of a velocity versus }

is relevant and can be applied for homotropic effector molecules since the heterotropic effector molecules have the possibility and affinity to change the sigmoidal curve to a more potential hyperbolic curve contingent upon the allosteric effector to be positive or negative modulator.

The expression isn't relevant for both homotropic and heterotrophic effectors since the two of them can tie to the allosteric site of allosteric enzymatic compounds.

The phrase \text{"works by altering the T/R ratio"} is significant and can be applied for both homotropic and heterotropic effectors.

The expression \text{"an enzyme's substrate"} is significant and applied for homotropic effectors just as when substrate molecules tie to the allosteric site of enzyme then it is regarded as homotropic effectors. The heterotropic effectors are effectors apart from substrate molecules.

The phrase \text{"alters the} \  K_m \ \text{ of an enzyme"} is not applied and insignificant to none of the heterotropic or homotropic effector molecules since K_m is significant for the enzymes that obey the Michaelis-Menten equation, but allosteric enzymes do not obey the Michaelis-Menten equation. Homotropic and heterotropic effectors are viable and efficient for allosteric enzymatic chemicals that don't contain
