channel protein

channel protein
Danh từ
Số nhiều: channel proteins

This term is a specialized biological descriptor used primarily in cellular biology and biochemistry. It describes a specific structural mechanism of the cell membrane, emphasizing the passive nature of the transport. Unlike carrier proteins, which undergo conformational changes to move solutes, channel proteins act as selective tunnels that allow molecules to flow down their concentration gradient.

In a technical context, the term is often used in discussions regarding membrane potential, osmotic balance, and signal transduction. It is a neutral, descriptive scientific term with no colloquial usage outside of academic or medical discourse.

Ý nghĩa

Danh từchannel protein

A pore-forming membrane protein that allows specific ions or molecules to pass through the cell membrane via passive diffusion.

The cell regulates its internal environment by opening and closing a specific channel protein.
