Question
What will trigger the opening of chemically gated ion channels?Multiple choice question.binding of neurotransmitter moleculeschanges in membrane potential
Solution
The opening of chemically gated ion channels is triggered by the binding of neurotransmitter molecules. These channels are sensitive to chemical changes in the environment. When a neurotransmitter molecule binds to the receptor site on the channel, it causes a conformational change that opens the channel and allows ions to pass through. Changes in membrane potential do not directly open these channels, as they are not voltage-gated.
