Answer:
Well protines come in diffrent shapes, for there diffrent functions. The first level, or primary structure, is the linear sequence of amino acids that creates the peptide chain. In the secondary structure, hydrogen bonding between different amino acids creates a three-dimensional geometry like an alpha helix or pleated sheet. An alpha helix is simply a spiral or coiled molecule, whereas a pleated sheet looks like a ribbon with regular peaks and valleys as part of the fabric. The tertiary structure describes the overall shape of the protein. Most tertiary structures are either globular or fibrous. Generally, nonstructural proteins such as enzymes are globular, which means they look spherical. The enzyme amylase is a good example of a globular protein. Structural proteins are typically long and thin, and hence the name, fibrous. Quaternary structures describe the protein's appearance when a protein is composed of two or more polypeptide chains. Often the polypeptide chains will hydrogen bond with each other in unique patterns to create the desired protein configuration.
some hormones are proteins; and some proteins are involved with digestion, respiration, reproduction, and even normal vision, just to mention a few.
f the three-dimensional structure of the protein is altered because of a change in the structure of the amino acids, the protein becomes denatured and does not perform its function as expected.

Answer:
A neuromuscular junction is a junction between a <em>nerve fiber</em> and a <em>muscle cell.</em>
Explanation:
<em>A neuromuscular junction (or myoneural junction) is a site of chemical communication between a nerve fiber and a muscle cell, is analogous to the synapse between two neurons. </em>
A motor neuron is able to transmit a signal to the muscle fiber, causing muscle contraction upon stimulation by a nerve impulse, the terminal releases the chemical neurotransmitter acetylcholine from synaptic vesicles binding to the receptors, the channels open, and sodium ions flow into the endplate, this initiates the end-plate potential, the electrical event that leads to contraction of the muscle fiber.
