Are viruses metabolically independent?

Are viruses metabolically independent?

Viruses do not have their own metabolism and require a host cell to make new products. They therefore cannot naturally reproduce outside a host cell—although bacterial species such as rickettsia and chlamydia are considered living organisms despite the same limitation.

Do viruses have their own metabolic system?

Viruses are non-living entities and as such do not inherently have their own metabolism. Altered cellular metabolism may aid in the survival of infected cells during the stress of viral infection.

Does a virus have an independent life cycle?

Virus do not have independent existence. To survive virus completes four stages in a host cell .

Which argument supports the idea that viruses are alive?

Which best explains why viruses do not have special structures?

Answer Expert Verified. Viruses can replicate inside a host that they infect this is the reason why viruses do not have special structure or enzymes that allows them to make their own food. They just replicate and infect but they never make their own food.

Which argument supports the idea that viruses are alive quizlet?

Which argument supports the idea that viruses are alive? Viruses contain unique genetic information. Which virus has a structure that includes an outer lipid bilayer that is studded with proteins? An enveloped virus is dependent on the envelope for its ability to infect a host cell.

What component of a virus is injected into?
