- What is the main source of carbon monoxide exposure?
- Incomplete combustion of carbon-based fuels
- Carbon monoxide binds hemoglobin to form ____, which prevents normal oxygen transport.
- carboxyhemoglobin
- How much higher is carbon monoxide's binding affinity for hemoglobin compared to oxygen?
- About 200 to 250 times higher

- What enzyme do organophosphate pesticides inhibit?
- Acetylcholinesterase
- What happens at synapses when acetylcholinesterase is inhibited by organophosphates?
- Acetylcholine accumulates excessively
