This is the secondary folding phase where hydrogen bonds between the side chains give you the alpha helix and the beta pleated sheet.

What organelles is responsible for folding protein in cell?
Rough endoplasmic reticulum.Rough endoplasmic reticulumB.Rough endoplasmic reticulum
Endoplasmic reticulum description?
NUCLEUS FUNCTION-Protein translocation, folding and transport or protein.
Is protein folding endergonic or exergonic?
it is endergonic because it reduces entropy
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.
Principles of protein structure?
Proteins have a number of 'levels' of structure associated with them: Primary, Secondary, Tertiatry and Quaternary.Primary StructureThe order of amino acids in a protein determines it's primary structure.Secondary StructureThe secondary structure is the simple folding of a protein into a shape. The two general shapes found are the alpha-helix (like a spiral) and the beta-pleated sheet (a little like the zigzag shape of a concertina). These shapes result from the intermolecular forces between R-groups on amino acids, and in the case of cystine, disulphide bridges.Tertiary StructureThe tertiary structure is a further layer of folding of the secondary structure. Single-chain proteins reach their final form with this layer of folding.Quaternery StructureOnly found in multi-unit protein complexes such as haemoglobin. This is a level involving the binding together of multiple protein chains to form a final structure. In the case of haemoglobin, this involves 4 main protein chains surrounding an Fe2+ ion.
The alpha helix and beta pleated sheet represent which level of protein structure?
The alpha helix and beta sheets are found at the Secondary level of protein folding. It's when the protein is taking its shape. Secondary structure
Is hemoglobin a protein that exhibits the quaternary structure of protein folding?
The tertiary structure is the folding
The alpha helix and pleated sheet are examples of?
secondary structure of a protein
What is the process in which protein are built?
Translation and transcription. Then they go into protein folding.
What type of protein shape is characterized by the alpha helix or a flat-pleated sheet?
secondary structure
What does Alpha helix and beta pleated sheets make up?
together they make a secondary protein structure
What organelles is responsible for folding protein in cell?
Rough endoplasmic reticulum.Rough endoplasmic reticulumB.Rough endoplasmic reticulum
What is secondary genetic code?
The secondary genetic code is the folding of protein.
What are the two most common secondary structures in a protein?
The two types of tertiary protein structures: globular and fibrous proteins. Globular proteins act as enzymes that catalyze chemical reactions in organisms. Fibrous proteins like collagen play structural role.
What is the four levels of proteins?
Proteins have primary structure, which is their amino acid sequence, secondary structure, which is either the alpha helix or the beta pleated sheet, tertiary structure, the protein's geometric shape, and quaternary structure, the arrangement of multiple protein subunits.
Which type of protein shields a newly forming protein from cytoplasmic influences while it is folding into its functional form?
Chaperonins
What special protein help a protein fold correctly?
A chaperone protein is used in the cell to ensure proper protein folding, among other cellular functions.
