What is the primary reason why ligand gated ion channels can exhibit a diverse range of structural and functional properties?
What is the primary reason why ligand gated ion channels can exhibit a diverse range of structural and functional properties?
- The different compositions of the multi-metric complexes that make up the channels (correct)
- The involvement of intermediate biochemical steps in the activation process
- The speed of the response (in milliseconds) due to direct activation of the channel
- The functional role of these receptors in synaptic transmission

How do ligand gated ion channels influence the electrical state of the cell membrane?
How do ligand gated ion channels influence the electrical state of the cell membrane?
- By playing an important functional role in synaptic transmission
- By directly activating intermediate biochemical steps
- By contributing to the diversity of structural and functional properties
- By directly influencing ion flow, leading to either hyperpolarization or depolarization (correct)
