Channel proteins

A) are binding sites for other molecules.
B) utilize the G protein complex to function.
C) are found only on endoplasmic reticulum.
D) allow cells to recognize one another.
E) provide a tunnel through which ions or molecules can enter or leave the cell.

Channel Proteins

Proteins embedded in cell membranes that facilitate the transport of ions and molecules across the membrane in a process essential for various cellular functions.

Endoplasmic Reticulum

A network of tubular membranes within the cytoplasm of the cell, involved in the production, processing, and transport of proteins and lipids.

G Protein Complex

A molecular switch on the inside surface of the cell membrane that plays a critical role in transmitting signals from extracellular stimuli to the cell's interior.
