Proteins, have a 3D shape because the amino acids are arranged in a helix (not a double-helix like DNA). The spiral is made because of the negative and positive poles in an amino acid. The positive pole drags the polypeptide to a negative pole at a different point in the chain.

What role does the tertiary structure of a protein play in determining its function?
The tertiary structure of a protein is crucial in determining its function because it determines the overall 3D shape of the protein. This shape is essential for the protein to interact with other molecules and perform its specific biological functions. Changes in the tertiary structure can alter the protein's function or render it non-functional.
What is the relationship between the function and structure of a protein?
Proteins are composed of amino acids, each of which have their own special properties. The non-polar amino acids would fold into the interior of the protein during protein folding, because they are hydrophobic. A protein consists of a primary structure, which consists of the amino acid chain. The secondary structure is how the amino acids join together into alpha helices and beta pleated chains and form hydrogen bonds. The tertiary structure is when disulphide bridges form, which maintain the protein's 3D shape, and the 3D shape begins to emerge. The quaternary structure is an assortment of several polypeptides, and constitutes the entire protein. The final shape of the protein determines its function.For example an enzyme carry out catalytic functions are mainly accomplished by it's catalytic core residues(place where substrate binds). when the 3D structure of protein is properly made(folded) then it is active, when a single residue is mutated or any improper folding leads to the enzyme either hyperactive, poorly active or inactive.
What is the word used to describe the distortion and inactivation of a protein by pH or heat?
Denatured protein. See attached Wikipedia Denatured Protein link. Denaturation. Proteins are fragile and its function depends on its 3D shape. High heat, salt concentration, pH, radiation etc will cause a protein to 'unravel' or change shape which leaves the protein nonfunctional. It is usually irreversible. Think of it as frying an egg. Eggs are protein right? When you fry an egg you change its shape and it is no longer opaque. You cannot unfry an egg.
A denatured protein or DNA molecules has lost what?
A denatured protein or DNA molecule has lost its native structure. This can be due to factors such as heat, pH changes, or chemical agents, resulting in the disruption of the non-covalent bonds that maintain the molecule's shape and function.
How does a protein's shape influence its function?
A protein's shape is crucial for its function because it determines how the protein interacts with other molecules. The specific shape of a protein allows it to bind to certain molecules, enabling it to carry out its specific biological functions. If a protein's shape is altered, it may not be able to perform its intended function effectively.
What is tertiary structure in protein?
The 3D shape or fold.
What types of bonds hold the 3d shape of a protein together?
The types of bonds that hold the 3D shape of a protein together are primarily hydrogen bonds, ionic bonds, disulfide bonds, and hydrophobic interactions. These bonds contribute to the stability and structure of the protein molecule.
What is the term for a protein losing its 3D shape?
A protein is "denatured" when it inflates or deflates due to pH level, heat, Ect. Not sure if that's what you meant by losing its shape, though
What is a net shape in a 3d shape?
It depends on the 3d shape.
What a 3d shape is a parallelogram?
It is not a 3D shape.
A protein folded into a globular shape in having only one polypeptide chain has what structure?
The protein would have a tertiary structure. This structure results from the unique folding of the single polypeptide chain into a 3D shape, giving the protein its functional conformation.
