Biochemists found that as active transporters in cell membranes undergo conformational changes to allow their main substrates to pass through through, small molecules like water slip through as well.

The alternative to active transport is passive transport, which uses kinetic energy only to move the molecules. Passive transport can only move molecules from a region of higher concentration to lower ...

(Nanowerk News) Inspired by micro-scale motions of nature, a group of researchers at the Indian Institute of Technology Madras and the Institute of Mathematical Sciences, in Chennai, India, has ...

Integral outer membrane receptors for iron chelates and vitamin B 12 carry out specific ligand transport against a concentration gradient. Energy for active transport is obtained from the ...

Defying one of biology’s more persistent dogmas, a potassium channel combines functions once thought to be invariably asunder. This channel, which is found in common bacteria, incorporates a subunit ...

Seeking students to contribute to research exploring motor-disease protein complexes and their role in intracellular transport, as they relate to disease initiation and the aging process, and the ...

Inspired by micro-scale motions of nature, a group of researchers has developed a new design for transporting colloidal particles, tiny cargo suspended in substances such as fluids or gels, more ...
