Final answer:
The TM helix in the membrane can provide information about its thickness, fluidity, permeability, rigidity, asymmetry, stability, and composition. It can also form channels through the membrane.
Step-by-step explanation:
The TM (transmembrane) helix in the membrane can provide information about its thickness and fluidity. The presence and arrangement of TM helices can affect the rigidity and permeability of the membrane. It also contributes to the asymmetry and stability of the membrane. Additionally, the TM helix can form channels through the membrane, allowing the passage of specific molecules.
