The function of a protein is dependent upon the shape into which the chain of amino acids folds. Many noncovalent interactions a
re responsible for maintaining the protein's shape. Assume you have isolated a protein from an organism in its proper shape, and you have treated it with an enzyme that selectively targets and breaks only the peptide bonds in the proteins. Would the protein retain its shape under these conditions? a. Yes; once noncovalent bonding determines the shape of a protein, the peptide bonds are no longer necessary.
b. Yes; because the noncovalent interactions that determine the shape of a protein are stronger than the peptide bonds.
c. No; while the noncovalent bonds determine the shape of a protein, the peptide bonds are required to hold the amino acids together.
d. Yes; but the shape would be affected to a greater extent by changes in temperature.
Answer: c). No; while the noncovalent bonds determine the shape of a protein, the peptide bonds are required to hold the amino acids together.
Explanation: Peptide bonds is a type of bond that covalently joins two or more amino acid molecules through a substituted amide linkage. Peptide bond is formed by the removal of the elements of water from the alpha carboxyl group of one amino acid and the alpha-amino group of another amino acid. When two amino acids molecules are joined by peptide bond, the resulting molecule is called a dipeptide, when three amino acids molecules are linked by two peptide bonds, a tripeptide is formed. When a few amino acids are joined by peptide bonds, the structure is called an oligopeptide, when many amino acids are joined, the product is called a polypeptide.
Since the enzyme breaks the peptide bonds, it means that the protein has been broken down into its constituent amino acid, therefore the protein has lost its primary structure and therefore will no longer retain its shape.
Your body needs protein to stay healthy and work the way it should. More than 10,000 types are found in everything from your organs to your muscles and tissues to your bones, skin, and hair. Protein is also a critical part of the processes that fuel your energy and carry oxygen throughout your body in your blood.
The term apomorphy means a specialized or derived character state; plesiomorphy refers to a primitive or ancestral trait. An same as autapomorphy is a derived trait that is unique to one group, while a same as synapomorphy is a derived trait shared by two or more groups.
The reason for Ovum being the correct answer, is because the Ovum is in the lower plant structure, and is the structure that is needed to be fertilized to reproduce gametes.
