Which effect follows when 'C3 convertase' activity fails?

💡 Explanation

Decreased C3 convertase activity reduces C3b deposition, crucial for opsonization, because C3b tags pathogens for destruction; therefore, opsonization is reduced rather than increased inflammation or altering T-cell responses directly.
