MEANING

A heart attack is a medical emergency. A heart attack usually occurs when a blood clot blocks blood flow to the heart. Without blood, tissue loses oxygen and dies.

A heart attack occurs when one or more of your coronary arteries become blocked. Over time, a coronary artery can narrow from the buildup of various substances, including cholesterol (atherosclerosis). This condition, known as coronary artery disease, causes most heart attacks.

CAUSES:

Chest Pain, Pressure, Fullness, or Discomfort.

Discomfort in other areas of your body.

Difficulty breathing and dizziness.  

Nausea and cold sweats.

The correct answer is option (A) membrane-disrupting toxins.

Membrane-disrupting toxins are not a method of avoiding host antibodies.

Phagocytes are first and primarily exposed to microorganisms invading tissues. Bacteria that are successful pathogens are those that rapidly draw phagocytes and can be quickly consumed and eliminated. Contrarily, most bacteria that are effective pathogens obstruct phagocytes' functions in some way or find another method to escape their attention.

Bacterial pathogens have developed a wide range of techniques to evade phagocytic engulfment and death. Most of them attempt to inhibit phagocytosis by blocking one or more of the stages. The chapter on Innate Immunity against Bacterial Pathogens discusses phagocytosis. There are many methods by that bacteria can evade phagocyte attention.

1. Pathogens can enter or stay limited to areas that phagocytes can't reach. Certain surface tissues, such as unbroken skin, and interior tissues, such as the lumens of glands and the urine bladder, are not monitored by phagocytes.

2. Some pathogens have the ability to prevent inducing a severe inflammatory response. The host cannot concentrate its phagocytic defenses in the absence of inflammation.

3. A few bacteria or their byproducts prevent the chemotaxis of phagocytes. For instance, even at very low doses, the phagocyte-killing substance streptococcal streptolysin reduces neutrophil chemotaxis. It is known that Mycobacterium tuberculosis fractions prevent leukocyte migration. Neutrophil chemotaxis is also prevented by the Clostridium toxin.

4. Some infections can coat the surface of the bacterial cell with an element that the host's phagocytes and immune system recognize as "self." Such a tactic conceals the bacterial cell's antigenic surface. Phagocytes are unable to identify bacteria when they come into contact with them, and antibodies' potential to opsonize them and increase phagocytosis is reduced. For instance, pathogenic Staphylococcus aureus makes clumping factor and cell-bound coagulase that clumps fibrin on the bacterial surface. The syphilis virus Treponema pallidum attaches fibronectin to its surface. Hyaluronic acid can be produced into a capsule by Group A streptococci. The ground substance (tissue cement) in connective tissue is hyaluronic acid.

Some pathogens can or do leave behind sialic acid residues on their surfaces, which hinders phagocyte detection and complement component opsonization.

Toxins that disrupt membranes is option (A), which is the right response.

Toxins that damage membranes cannot be used to get around host antibodies.

Invading microorganisms first and foremost come into contact with phagocytes. Successful pathogens of bacteria are those that swiftly attract phagocytes and can be eaten up and eliminated. On the other hand, the majority of bacteria that are potent pathogens interfere with phagocyte functions or find another way to avoid their detection.

Bacterial pathogens have created a variety of strategies to avoid being engulfed by phagocytic cells and dying. Most of them make an effort to stop one or more of the phases of phagocytosis. Phagocytosis is covered in the chapter on Innate Immunity against Bacterial Pathogens. Bacteria can avoid phagocyte attention in a variety of ways.

1. Pathogens are able to infiltrate or remain confined to places that phagocytes cannot. Certain inner tissues, such as the lumens of glands and the urinary bladder, as well as certain surface tissues, such as intact skin, are not observed by phagocytes.

2. Some pathogens are capable of preventing the initiation of a serious inflammatory response. Without inflammation, the host cannot focus its phagocytic defenses.

3. A few bacteria or their metabolites stop phagocytes from chemotactically moving. For instance, the phagocyte-killing agent streptococcal streptolysin lowers neutrophil chemotaxis even at very low levels. Leukocyte migration is known to be inhibited by Mycobacterium tuberculosis fractions. The Clostridium toxin also inhibits neutrophil chemotaxis.

4. In some infections, an element that the host's phagocytes and immune system perceive as "self" may be present on the surface of the bacterial cell. Such a strategy hides the antigenic surface of the bacterial cell. When phagocytes come into touch with bacteria, they are unable to recognize them, and antibodies' ability to opsonize them and boost phagocytosis is diminished. To clump fibrin on its surface, pathogenic Staphylococcus aureus produces clumping factor and cell-bound coagulase. Treponema pallidum, the cause of syphilis, binds fibronectin to its surface. Group A streptococci have the ability to synthesize hyaluronic acid into a capsule. Hyaluronic acid serves as the tissue cement (the ground substance) in connective tissue.

Sialic acid residues left by some pathogens on their surfaces can or do prevent phagocyte detection and complement component opsonization.

To test to for the presence of sugar, the solution to be used is called the Benedicts Solution. The other solution to use is the Iodine solution.

Both Benedict's solution and iodine solution are commonly used to test for the presence of sugars and starch, respectively. By testing the mystery solution with both of these solutions, you can determine whether it contains sugar or starch, or both.

It is important to test the mystery solution with both Benedict's solution and iodine solution because different types of sugars and carbohydrates can have different chemical properties, and therefore may not be detected by a single testing solution. Lugol's iodine, commonly known as aqueous iodine or strong iodine solution, is a water-based solution containing potassium iodide and iodine.

Testing with multiple solutions helps to ensure a more accurate and complete analysis.

The main reason that we can use antibiotics that interfere with protein synthesis in bacteria without being affected ourselves is because of the difference in ribosomal sites between bacteria and eukaryotes. The correct answer is option а. Antibiotics bind to the ribosomal sites in the bacteria, which are different than those found in eukaryotes, to interfere with protein synthesis.

This difference in ribosomal sites allows the antibiotics to specifically target the bacteria without affecting our own cells. The other options are incorrect because antibiotics do not bind to mitochondrial sites (option b), they do not affect both prokaryotic and eukaryotic cells equally (option c), and the size of eukaryotic ribosomes is not the reason why antibiotics cannot bind to them (option d).

In conclusion, the main reason that we can use antibiotics that interfere with protein synthesis in bacteria without being affected ourselves is because of the difference in ribosomal sites between bacteria and eukaryotes. This allows the antibiotics to specifically target the bacteria without affecting our own cells.

During the Guides phase of HIV disease, the insusceptible framework turns out to be seriously compromised, prompting a pattern of progressively extreme side effects. This cycle happens because of the accompanying elements:

Declining CD4+ Lymphocytes: HIV explicitly targets and obliterates CD4+ White blood cells, which assume a pivotal part in planning a safe reaction. As the infection duplicates and contaminates more CD4+ Lymphocytes, their numbers decline, debilitating the insusceptible framework's capacity to actually ward off diseases and sicknesses.

Pioneering diseases: With a debilitated insusceptible framework, people with Helps become defenseless to deft contaminations. These are contaminations brought about by organic entities that normally don't cause extreme disease in individuals with sound safe frameworks. Deft contaminations can go from bacterial, viral, parasitic, and protozoal diseases. These diseases can be extreme, relentless, and testing to treat, adding to the deteriorating of side effects.

Industrious aggravation: Persistent safe actuation and irritation are signs of HIV contamination. The continuous insusceptible reaction and aggravation further harm the safe framework and imperative organs after some time. This tireless irritation can prompt the advancement of unexpected complexities, like cardiovascular illness, neurological issues, and certain malignant growths, which add to the movement of side effects.

HIV transformations and viral variety: HIV has a high change rate, prompting the improvement of viral variations that can dodge the safe framework and antiretroviral treatments. As the infection advances, it turns out to be harder to control and treat, adding to the deteriorating side effects and treatment challenges.

Generally speaking, the pattern of progressively extreme side effects during the Guides phase of HIV contamination is driven by the dynamic obliteration of the safe framework, powerlessness to shrewd contaminations, persevering aggravation, and viral changes that compromise the body's capacity to protect against contaminations and illnesses.

The double membrane structure is unique to the mitochondria and it is made up of inner and outer mitochondrial membranes that are separated by an intermembrane gap.

Numerous folds (called cristae) in the inner membrane extend into the matrix of the organelle. The inner membrane and matrix are the two main functioning compartments of mitochondria, and each of these parts has a specific functional purpose. Along with the enzymes in charge of the key oxidative metabolic processes, the matrix houses the mitochondrial genetic system. In animal cells, the primary source of metabolic energy is the oxidative breakdown of glucose and fatty acids. Glucose is converted to pyruvate in the cytosol during the first stages of glucose metabolism (glycolysis). The majority of the usable energy (ATP) produced by the metabolism of glucose is then produced after pyruvate has been delivered into mitochondria and completely oxidized to CO2.
