Question

question 1-1
which statement best describes how viruses disrupt normal cellular processes to cause disease?
○ viruses use cell machinery to build products the virus needs.
○ viruses release large amounts of energy into the cell, causing increased growth rates.
○ viruses release antibiotics that destroy the cell membrane so more viral particles can be released.
○ viruses block gene expression and prevent host cell dna replication.

Explanation:

Viruses are obligate intracellular parasites; they lack their own cellular machinery for replication, protein synthesis, and energy production. Instead, they hijack the host cell's ribosomes, enzymes, and energy resources to produce viral components, which disrupts the host's normal cellular functions and leads to disease. The other options are incorrect: viruses do not release antibiotics, they do not add energy to the cell, and while some may interfere with host processes, the core mechanism of disruption is usurping cell machinery.

Answer:

A. Viruses use cell machinery to build products the virus needs.
