What cycle makes the host cell burst?

• A. Lysogenic
• B. Glycolysis
• C. Fermentation
• D. Lytic

Answer: (D)

The main idea is how a virus reproduces inside a cell and at what point the cell is damaged. In the lytic cycle, the virus takes over the cell’s machinery, rapidly makes many new viral particles, and then breaks the cell open to release them. This bursting, or lysis, of the host cell is a hallmark of the lytic cycle. By contrast, the lysogenic cycle hides the viral DNA inside the host genome and doesn’t cause immediate cell destruction. Glycolysis and fermentation are normal metabolic pathways for breaking down sugars to release energy and do not involve viruses causing the host cell to burst. So the cycle that makes the host cell burst is the lytic cycle.
