This movement is against the concentration gradient so the transport proteins require an energy supply. Energy is provided by the breakdown of ATP inside the cell. This diagram shows molecules ...

Scientists at Osaka University have designed a nanogate that opens and closes using electrical signals, offering precise ...

When in motion, the electrons inside the molecules form what's known as plasmons, collectively vibrating entities that drive movement across the whole of the molecule. "What needs to be ...

Other signaling molecules must move much farther to reach ... whereas similar cells in the ear react to the movement of sound waves. In addition, specialized cells in the human vascular system ...

Osaka University researchers developed an electrically controlled nanogate, enabling precise regulation of ion transport and ...

And when you dip the detergent down into the milk or bring it to the food coloring at the edge of the plate, there is usually some more swirling and movement of color. The negative charge on the ...

The answer to this problem is to enclose the cytoplasm with a membrane that prevents the free movement of molecules. As described above, a nonpolar material would work well for this membrane ...
