HHMI researchers suggest that defective cell transport may play a role in Alzheimer’s disease. Over the last few years, scientists have been successful in identifying genes implicated in Alzheimer’s ...

In pure water, the cell contents (the cytoplasm and vacuole) push against the cell wall and the cell becomes turgid . Fully turgid cells support the stems of non-woody plants. In a very ...

Most of us rely heavily on shipping services like FedEx or UPS to ensure we receive the correct packages. If that system was ...

Transport of molecules within a cell and out of the cell requires a complex endomembrane system. Endocytosis occurs when the cell membrane engulfs particles (dark blue) outside the cell ...

The targeting of transport vesicles to the correct membrane ... based cytoskeletons to bring a vesicle from one part of the cell to another. Then tethering proteins collect and restrain vesicles ...

The slideshow shows an example of osmosis showing the direction of movement of water between two different concentrations of sugar solutions: Under normal circumstances, the cells in all organisms ...

Ron Kaback didn’t believe that electrochemical gradients could power the transport of sugars and amino acids across cell membranes—until he proved that they do. The measles virus attacks long-lived ...

Hydrogen fuel cells offer an eco-friendly alternative to fossil fuels by generating electricity with only water as a byproduct. Investing in green hyd ...

Just as cities must carefully manage the flow of cars in and out of downtown, cells regulate the movement of molecules into ...
