The virus that causes rabies travels up nerve cells to the brain and spinal cord. which cell structures will allow the virus to move through the nerve cells?
The virus that causes rabies travels up nerve cells to the brain and spinal cord. Endosomes cell structures will allow the virus to move through the nerve cells
The main function of endosomes is intracellular sorting. They control the movement of proteins and lipids between the plasma membrane Golgi, the trans-Golgi network (TGN), and vacuoles and lysosomes, among other subcellular compartments in the secretory and endocytic pathway.
Endocytic carrier vesicles move materials destined for lysosomal breakdown from early endosomes to late endosomes. Later, late endosomes merge with transport vesicles carrying lysosomal hydrolases from the trans-Golgi network (TGN), maturing them into lysosomes.

What is the key difference between the oxidation of glucose to carbon dioxide in a calorimeter and the biological oxidation of glucose in the human body?
Key difference between the oxidation of glucose to carbon dioxide in a calorimeter and the biological oxidation of glucose in the human body is that the living organism captures some of the energy as chemical energy.
Complete oxidation of one molecule of glucose results in the production of the equivalent of 38 molecules of ATP. This results in the production of 38 molecules of water, because formation of the phosphodiester bond between ADP and inorganic phosphate involves the splitting off of a molecule of water. Oxidation of glucose in a calorimeter is completely inefficient. The products of oxidation are carbon dioxide and water, and all of the energy produced is released as heat.

Which type of amino acid replacement is least likely to result in the disruption of protein structure and function?
In order to determine whether the new amino acid being replaced has distinct properties, we must first record which features of the amino acid each location possesses. At physiological pH, the side chains of some amino acids will be negatively charged, others positively charged, and yet others will be neutral.
Methionine and arginine have chemically distinct properties. While arginine is a positively charged amino acid and would presumably be facing the protein outside, methionine is a nonpolar side chain that would likely be hidden inside the protein core. The structure of a protein would likely be altered or disrupted if arginine were substituted for methionine.

Shock is a condition in which the body's circulatory system fails to maintain a sufficient flow of blood to its important organs.
What is "shock" & how can one identify it?
Shock is a serious medical illness caused by an abrupt decrease in blood flow to the body. Because of inadequate blood flow maintained by the circulatory system, essential organs receive much less oxygen and nutrients. Additionally, it weakens the kidneys, which limits the body's ability to eliminate waste. Numerous factors, such as insufficient blood volume and insufficient cardiac blood flow, can contribute to shock.

Why is postoperative pain controlled most effectively by giving preemptive analgesic/s before the surgical procedure is carried out?
Preemptive analgesia, a developing clinical concept, is starting an analgesic regimen before the onset of painful stimuli in order to avoid making the nervous system more sensitive to pain-inducing stimuli in the future.
Pre-emptive analgesia is an antinociceptive medication administered prior to an incision or surgery, thus it's crucial to keep in mind when it should be administered. This aids in avoiding the development of altered afferent input processing, which would otherwise exacerbate postoperative pain.The three intravenous opioids that are most frequently used to treat postoperative pain are morphine, hydromorphone (dilaudid), and fentanyl.
