Saturated fatty acids are different to unsaturated fatty acids because they have no C=C double bonds.
<h3>What are the differences between saturated and unsaturated fatty acids?</h3>
- Saturated fatty acids do not have C=C double bonds, while in unsaturated fatty acids there is at least one C=C double bond in the fatty acid chain.
 - Saturated fats are usually solid at room temperature and are derived from animal sources, whereas unsaturated fats are usually liquid at room temperature and are from plant sources.
 - One must reduce the amount of saturated fat in their diet and consume more unsaturated fats like olives, seeds and nuts.
 - Unsaturated fats can be monounsaturated (contains only C=C double bond) or polyunsaturated (contains two or more C=C double bonds).

Answer:
Botulism toxin disrupts motor control <u>by blocking the release of acetylcholine by motor neurons.   </u>
Explanation:
Acetylcholine is the principal neurotransmitter in motor neurons. If there is no release of acetylcholine from the presynaptic motor neuron, the ion channels will not open. If the ion channels do not open, Na+ cannot enter the postsynaptic membrane to start an action potential. As a result, the muscle can not move.
The ion channels have a specif receptor for acetylcholine. When acetylcholine binds to the receptors, the channels open. With the ion channels open, Na+ can enter the postsynaptic membrane to start an action potential. This does not happen in the presence of botulism toxin since it blocks the release of acetylcholine.
