TOR (target of rapamycin) is a conserved serine/threonine kinase forming two functionally distinct complexes (TORC1 and TORC2) and controlling cell growth upon integration of environmental cues such ...
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 ...
AMHERST, Mass. – Inside many growing cells, an active transport system runs on nano-sized microtubule tracks that resemble a highway, complete with motors carrying cargo quickly from a central supply ...
Proceedings of the National Academy of Sciences of the United States of America, Vol. 78, No. 6, [Part 2: Biological Sciences] (Jun., 1981), pp. 3446-3449 (4 pages) Membrane vesicles from Salmonella ...
Glucose serves as a major source of energy for metabolic processes in mammalian cells. Since polar molecules cannot be transported across the plasma membrane, carrier proteins called glucose ...
Boron, though required only in minimal amounts, is vital for plant development. It strengthens cell walls and supports the growth of roots and shoots. Normally, boron, in the form of boric acid, is ...
