Proteins are made up of long chains of amino acids, just a chain of ami. tacids makes up the primary structure. The secondary structure is formed by hydrogen bonds joining the chains in certain places to make an alpha helix or a beta sheet.

An impulse hits the nerve and travels to the synapse.Molecules odf the neurotransmitter substance are released and diffuse across gaps to fit into the protein receptor molecules, this results in nerve impulse in the second neurone. Enzymes are also proteins and play a massive part in speeding up reactions.
