Rhodopsin is a light sensitive G-protein coupled receptor with retinal (red) as cofactor.  that stimulates the G-protein transducin (blue), which releases GDP and binds GTP (yellow) resulting in the liberation of its  subunit (light blue).  Source: PDB entry 6oy9
A ball and stick + ribbons model of beta-secretase - a protein that is important in forming healthy peripheral nerve cells, but is also involved in the onset of Alzheimer's disease.

Gram-negative bacteria may develope resistance and expel antibiotic molecules through the TolC efflux-pump. They employ efflux pumps to expel unwanted materials from their cytoplasm.
The protein responsible for Alzheimer's disease has recently been identified. It has been suggested that plaques formed by amyloid-β sheets may interfere with transmission at neuronal synapses. This image uses images of the plaques and the atrophied brain caused by Alzheimer's disease as a backdrop to illustrate the horror of the disease and the realistic phenomenon in vivo.
