An essential nutrient<span> is a </span>nutrient<span> that the body cannot synthesize on its own -- or not to an adequate amount -- and must be provided by the diet. These</span>nutrients<span> are necessary for the body to function properly. On the other the non-essential ones cannot be made inside the body so they are acquired from the food we eat.</span>
Answer:
The structure that is in physical contact with the auditory receptor stereocilia is the tectorial membrane.
Explanation:
The tectorial membrane is a structure or a thin layer of tissue that is floating in the endolymph on the stereocilia of the ciliated cells. Ciliated cells, which are sensory cells attached to the surface of the basilar membrane.
When the ciliated cells move up and down, microscopic projections similar to sows (known as stereocilia), which are located above the ciliated cells, cause the cilia to lean towards the side wall of the cochlea. This inclination makes that some channels that look like pores open, which are at the tips of the stereocilia. When this happens, certain chemicals enter the cells, thus generating an electrical signal. The inner ciliated cell is activated, probably by a direct contact of its stereocilia with the Hensen band of the tectorial membrane, the synapse between the ciliated cell and the auditory nerve fibers, send a message to the brain, which converts it into sounds that we can recognize and understand.

Enzyme synthesis cannot be a function performed by a membrane protein.
<u>Explanation:</u>
Membrane protein is found on the lipid bilayer that surrounds the cell. Enzymes are the globular structures of proteins which are made by the translation of the specific m-RNA in the cytosol of the cell and not by the membrane proteins. While a membrane protein can be used as a pump to transport ions across the membrane, it can be used for cell-cell or cell-matrix adhesion and as a hormone binding protein.
