Question

The K⁺ ion channel is a trans-membrane protein complex that transports K⁺ ions across the plasma membrane. Which description of the protein is likely true?

1) It is a channel that transports Na⁺ ions
2) It is a channel that transports Cl⁻ ions
3) It is a channel that transports K⁺ ions
4) It is a channel that transports Ca₂⁺ ions

Answer 1

The K+ ion channel is a protein that transports K+ ions across the plasma membrane.

Step-by-step explanation:

The K+ ion channel is a trans-membrane protein complex that transports K+ ions across the plasma membrane. Therefore, the correct description of the protein is option 3) It is a channel that transports K+ ions.
