Ion channels that open in response to a chemical signal are called:

A Voltage-gated

B Ligand-gated

C Mechanically gated

D Leak channels

✓ Correct Answer: Option B

Ligand-gated ion channels open when a specific chemical (neurotransmitter, hormone) binds to the receptor.

💡 Why is B) the correct answer?

The correct answer to the question "Ion channels that open in response to a chemical signal are called:" is Option B: Ligand-gated.

The other options — A) Voltage-gated, C) Mechanically gated, D) Leak channels — are incorrect for this Everyday Science question. As explained above: Ligand-gated ion channels open when a specific chemical (neurotransmitter, hormone) binds to the receptor.
