Heinz bodies, which may result in hemolytic anemia, can be formed by the following changes to hemoglobin EXCEPT?

Medicine
1 answer:
s2008m [1.1K]2 years ago
6 0

Answer:

C) substitutions that reduce the affinity of hemoglobin for oxygen

Explanation:

Heinz bodies are inclusions in the eritrocite, filled by denaturalized globin (protein part of the hemoglobin). Hemoglobin is formed by 4 globin subunits (2 alpha chains and 2 beta chains) plus a heme group. The latter, is responsible for oxygen binding.

The denaturalization of the globin is caused by substitutions that do not allow the protein to fold properly and bind the heme group accordingly. This is the cause of the Heinz bodies in the eritrocite. Therefore, this is a structural problem that impedes the protein to fold into a functional protein and has nothing to do with hemoglobin having less affinity for oxygen. In the last mentioned case, the protein is still functional but poorly binds oxygen, hence, does not for Heinz bodies.

Which natural phenomena will over the next 13,000 years gradually cause the northern hemisphere to experience summer during toda
ANTONII [103]

Answer:

Earth's tilt towards the sun will gradually cause the northern hemisphere to experience summer during today's current winter.

Explanation:

It is expected that over the next 13,000 years, the polar region, particularly the north pole will be tilted gradually towards the sun. At that time, the earth will be in the closest position towards the sun. The tilt would be along the axis and also orbital. Henceforth this both forms of earth's tilt towards the sun, will expose the northern hemisphere to maximum solar radiation, this will cause the region to experience summer during winter's time.

Common behaviors that are a result of Alzheimer's disease are
Liula [17]

Answer:

angry outbursts and physical aggression, hand wringing pacing and rocking, accusing loved ones of wrong doing and hallucinating, repeating stories and leaving the house unassisted, sleep problems and sundowing

Explanation:

1, Verbal or physical aggression, which can be quite alarming, is common in patients with Alzheimer’s.

2, Dementia makes it very difficult to process stimuli and new information, causing many people with Alzheimer’s disease to become anxious. 

3, Caregivers may feel at a loss when an Alzheimer’s patient exhibits behavior that is clearly not grounded in reality: either hallucinations—perceiving something that isn’t really there—or delusions, which are false beliefs that can lead to paranoia.

4, The memory problems caused by Alzheimer’s disease can lead to a range of distressing behaviors, including repetition of words or activities, disorientation even in familiar places, and, in severe cases, confusion about the passage of time.

5, It’s not well understood why sleep disturbances occur in many Alzheimer’s patients, but it’s common for them to experience nighttime restlessness and changes to their sleep schedule.

A 17-year-old male develops pneumonia, diabetic ketoacidosis, and metabolic acidosis. Respiratory compensation to a metabolic ac
e-lub [12.9K]

Answer:

The best answer from the choices, to the question: The cause of the hyperventilation is described by which of the following statement:___, would be, B: A decrease in the bicarbonate concentration stimulates ventilation.

Explanation:

The acid-base balance in the human body, is a very restrictive one. Normal ranges in this base are: 7.35 to 7.45. Whenever the values go either below 7.35 or above 7.45, we are talking about a person going into acidosis or alkalosis. Both situations are pretty serious and they have to do with the balance between the amounts of bicarbonate, and CO2 in the form of carbonic acid, in the blood. The normal ratio of bicarbonate to carbonic acid, is usually 20:1. Chemoreceptors, especially central ones in the neck, measure constantly that the balance is kept and if this is not the case, then several mechanisms will be put into place to recover it. One such measure is respiratory, and the other is metabolic. In the case of this 17-year-old, he has a pneumonia, which means that from the start, one of his recovery mechanisms is impeded, which is the respiratory mechanism of balance. He is also having metabolic problems with his system of compensation because his body is already producing high levels of H+ ions and not enough bicarbonate. Hyperventilation in this person is attempting to expel as much CO2 as possible, to try and restore the balance. The first thing that is sensed by the receptors is the changing in the 20:1 ratio, the increase in pH due to too much carbonic acid, and thus the body initiates the use of CO2 expulsion by the lungs, while metabolic mechanisms come into play.
