The helicity amplitudes of the N(1520) and N(1535) resonances in the electromagnetic transition are studied in the constituent quark model using the impulse approximation, with the proton and resonances assumed to be in three-quark configurations. The comparison of theoretical results and experimental data on the helicity amplitudes 
, 
, and 
indicates that the N(1520) and N(1535) resonances are primarily composed of three-quark 
states but may contain additional components. However, it is improbable that contributions from meson clouds will be dominant at low
