It is receptors which interact with the antibiotic so as to permit it inside the cell. Therefore, in the absence of receptors, it doesn't matter how much antibiotic is lying in the external environment of that bacteria, the antibiotic will not be able to enter the bacterial cell to kill it. Hence, the bacteria will be able to survive easily.
