What determine the shape and function of a protein?
Conformation is what determines a protein's unique set of functional and otherwise shapes.
What is a fibrous protein that gives shape to an RBC plasma membrane?
Spectrin is a fibrous protein that helps give shape to the red blood cell plasma membrane. It plays a critical role in maintaining the flexibility and stability of the membrane, allowing red blood cells to deform as needed to pass through narrow capillaries.
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.
How does protein confirmation affect its function?
Protein conformation is critical for its function as it determines the interactions the protein can have with other molecules. A protein needs to fold into the correct 3D shape to perform its specific biological activity. Any changes in conformation can disrupt the protein's ability to bind to other molecules or catalyze reactions, leading to a loss of function.
Are enzymes still functional after losing their shape?
enzymes are still functional after losing their shape as they depend onn their shape
What shape of a protein molecule resembles?
Protein molecules can have various shapes, such as globular, fibrous, or membrane-bound. The shape of a protein is important for its function, with globular proteins often being enzymes or transport molecules, and fibrous proteins providing structural support. Additionally, the shape of a protein is determined by its specific sequence of amino acids.
Globular or fibrous polypeptide chains are what type of protein structure?
Fibrous polypeptide chains are a type of protein structure known as secondary structure, while globular polypeptide chains are associated with tertiary structure. Globular proteins typically have a compact, rounded shape, while fibrous proteins have a more elongated, fibrous shape.

A denatured protein may re-form to its funtional shape when returned to its normal enviorntment What does that indicate about a protein's confirmation?
It indicates that the protein's functional shape is stable and can be recovered under appropriate conditions. This suggests that the protein's native conformation is thermodynamically favorable over time.
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.
The shape of most protein molecules may be described as?
The shape of most protein molecules may be described as a specific three-dimensional structure, typically categorized into primary, secondary, tertiary, and quaternary structures. These structures are formed by the folding and interactions of the protein's amino acid sequence, creating a functional and unique shape that determines the protein's biological function.

Is an enzyme a structural protein or functional protein?
Yes, enzymes are proteins and it is their sequence of amino acids (primary structure) that determines what kind of an enzyme it is and makes all the enzymes unique and it is the tertiary structure of enzymes that maintains their shape and give rise to the unique active site. When an enzyme is denatured, it loses its tertiary structure and therefore its shape.
How does acids denature proteins?
Acids disrupt the hydrogen bonds and electrostatic interactions that hold the protein structure together, causing the protein to unfold and lose its functional shape. This disrupts the active sites of the protein and can lead to loss of function.
What is meant by the term folding?
In biology, folding refers to the process by which a protein's linear amino acid sequence adopts a specific three-dimensional shape to carry out its function. This folding process is critical for the protein to be functional.
