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

A plasma membrane is permeable to specific molecules that a cell needs. Transport proteins in the cell membrane allow for selective passage of specific molecules from the external environment.

Researchers explore how natural compounds in traditional Chinese medicine can modulate cholesterol metabolism to combat ...

A new study by McGill University researchers yields insights into how the disruption of calcium transport in the brain is linked to autism and intellectual disability.

The current cisternal maturation model proposes that these vesicles are transport vehicles for Golgi enzymes rather than for protein cargo. Retrograde vesicles that travel backward through the ...

In living organisms, every protein—a type of biological polymer consisting of hundreds of amino acids—carries out specific ...

This takes place when molecules diffuse across the cell membrane by travelling through specific transport proteins. It occurs down a concentration gradient - molecules move from an area of high to ...
