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 ...

Light can be used to control the transport of proteins from the cell nucleus with the aid of a light-sensitive, genetically modified plant protein. Biologists working in the field of optogenetics have ...

Scientists have developed simple new proteins almost devoid of chemical diversity that still play a surprisingly active and specific role in cellular function, causing cells to act like cancer cells.

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 ...

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 ...

Protein aggregation and active principle ingredients (API) stability are factors that ultimately impact both the usability and quality of many biopharmaceutical products, especially injectables. The ...
