Researchers uncover mechanism of protein transport in mitochondria

The research labs of Dr. Thomas Becker and Dr. Nikolaus Pfanner from the Institute for Biochemistry and Molecular Biology at the University of Freiburg have reported a function of the metabolite channel of the mitochondrial ...

When the seed becomes a plant, it has 48 hours to survive

During germination, the embryo within a seed must develop into a young seedling capable of photosynthesis in less than 48 hours. During this time, it relies solely on its internal reserves, which are quickly consumed. It ...

Nanoscale velcro used for molecule transport

Biological membranes are like a guarded border. They separate the cell from the environment and at the same time control the import and export of molecules. The nuclear membrane can be crossed via many tiny pores. Scientists ...

Cells use import machinery to export their goods as well

(PhysOrg.com) -- In the bustling economy of the cell, little bubbles called vesicles serve as container ships, ferrying cargo to and from the port — the cell membrane. Some of these vesicles, called post-Golgi vesicles, ...
