The first part is the stimuli receiver, such as the retina of an eye. Then the information goes to the sensory neuron, which is connected to the stimuli receiver.
Then the information goes to the central nervous system- the brain!
The brain then sends the information to the motor neuron, which sends it to the muscle (the first option is the correct one)
Proteins have up to four levels of organic structure.
1.Primary structure - the linear arrangement of amino acids.
2. Secondary structure - areas of folding or coiling within a protein.
3. Tertiary structure - the final three dimensional structure of a protein.
4. Quaternary structure - non covalent associations that bind multiple polypeptides into a single larger protein. E.g. hemoglobin has four polymers, two alpha and two beta chains. They are non covalently bound to each other to form a single large protein - hemoglobin.
