Multiple Choice

Why are viruses referred to as obligate intracellular parasites in the context of organic chemistry?

Because they are capable of photosynthesis within host cells.

Because they require host cell machinery to replicate and survive.

Because they can replicate independently outside of host cells.

Because they produce their own energy and proteins without a host.

Verified step by step guidance

Understand the term 'obligate intracellular parasites': In the context of biology and organic chemistry, this term refers to organisms that cannot complete their life cycle without exploiting a suitable host cell.

Recognize the nature of viruses: Viruses are not considered living organisms because they lack the cellular machinery necessary for self-replication and metabolism.

Identify the dependency of viruses: Viruses must enter a host cell to utilize the host's cellular machinery, such as ribosomes and enzymes, to synthesize viral proteins and replicate their genetic material.

Clarify why viruses cannot replicate independently: Unlike bacteria or other microorganisms, viruses do not have the necessary components to carry out metabolic processes or reproduce on their own outside of a host cell.

Conclude with the correct reasoning: Viruses are referred to as obligate intracellular parasites because they require the host cell's machinery to replicate and survive, not because they can perform photosynthesis or produce their own energy independently.
