You are working in a laboratory trying to determine how a virus infects its host cells. You make an interesting observation, which is that if you prevent endosomes or lysosomes from acidifying, using a drug that blocks H+ATPases, the number of viruses entering cells is greatly reduced. Provide an explanation for this finding.
