Question

Assess the following statements, and select those that correctly apply to the properties of exotoxins and endotoxins. Check All That Apply Exotoxins typically cause systemic effects, whereas endotoxins precisely target a specific tissue type; e.g., neurological tissue. Exotoxins typically cause systemic effects, whereas endotoxins precisely target a specific tissue type; e.g., neurological tissue. Exotoxins are made of protein that are synthesized and secreted by a living cell, whereas endotoxins are comprised of lipopolysaccharide found in the outer membrane of gram-negative bacteria. Exotoxins are made of protein that are synthesized and secreted by a living cell, whereas endotoxins are comprised of lipopolysaccharide found in the outer membrane of gram-negative bacteria. Endotoxins demonstrate potent toxicity; their lethal dose is low compared to exotoxins, which require a high dose to cause disease manifestations. Endotoxins demonstrate potent toxicity; their lethal dose is low compared to exotoxins, which require a high dose to cause disease manifestations. Hemolysins are examples of endotoxin. They may exhibit β-hemolysis, complete lysis of erythrocytes; or α-hemolysis, partial lysis which manifests as a greenish tinge on blood agar.

Answer 1

Answer:

Option 3 and 4 (option is same).

Explanation:

Exotoxins may be defined as the produced by the bacteria and cause strong immune reactions. Endotoxins are toxins present in the bacteria that are not capable of inducing an strong immune response.

These exotoxins are proteinaceous in nature and are secreted by both the gram positive and gram negative bacteria. Endotoxins contains lipopolysaccharide present on the outer membrane of only gram negative bacteria.

Thus, the correct answer is option (3 and 4).
