Questions: Multiple Choice Question The purpose of storage granules produced by some bacteria is to store o toxins o virulence factors o peptidoglycan o nutrients

The answer is the last one: nutrients.

Explanation for each option:

• Toxins: Storage granules in bacteria are not typically used to store toxins. Toxins are often secreted by bacteria to affect host organisms, rather than being stored internally.

• Virulence factors: While virulence factors are important for the pathogenicity of bacteria, they are not stored in granules. Virulence factors include a variety of molecules like proteins and enzymes that help bacteria infect hosts, but these are not stored in granules.

• Peptidoglycan: Peptidoglycan is a major component of bacterial cell walls, not something stored in granules. It provides structural support and shape to the bacterial cell.

• Nutrients: Storage granules in bacteria are primarily used to store nutrients. These can include carbon sources like glycogen or polyhydroxybutyrate, phosphate in the form of polyphosphate, or sulfur. These stored nutrients can be used by the bacteria when external resources are scarce.

In summary, storage granules in bacteria are used to store nutrients, which can be utilized when needed.
