Which of the following (could be more than one) would not be a rational explanation for why the three-dimensional structure of a protein is driven and stabilized largely by noncovalent rather than covalent bonds? a) Proteins may be degraded for energy, and if their three-dimensional structures were held together by mostly covalent bonding, this might be too difficult to accomplish b) Proteins will need to be unfolded to cross biological membrane, and if their three-dimensional structures were held together by mostly covalent bonding, this might be too difficult to accomplish. c) Protein function (transport, enzyme catalysis, etc...) may require flexibility in the three- dimensional structure to allow for conformational change, and if protein three-dimensional structure were held together by mostly covalent bonding, this might be too difficult to accomplish. d) All of the answer choices are rational explanations for why the three-dimensional structure of protein is driven and stabilized largely by noncovalent bonds rather than mostly covalent bonds
Proteins
We generally tend to think of proteins only from a dietary lens, as a component of what we eat. However, they are among the most important and abundant organic macromolecules in the human body, with diverse structures and functions. Every cell contains thousands and thousands of proteins, each with specific functions. Some help in the formation of cellular membrane or walls, some help the cell to move, others act as messages or signals and flow seamlessly from one cell to another, carrying information.
Protein Expression
The method by which living organisms synthesize proteins and further modify and regulate them is called protein expression. Protein expression plays a significant role in several types of research and is highly utilized in molecular biology, biochemistry, and protein research laboratories.
Which of the following (could be more than one) would not be a rational explanation for why the three-dimensional structure of a protein is driven and stabilized largely by noncovalent rather than covalent bonds?
a) Proteins may be degraded for energy, and if their three-dimensional structures were held
together by mostly covalent bonding, this might be too difficult to accomplish
b) Proteins will need to be unfolded to cross biological membrane, and if their three-dimensional
structures were held together by mostly covalent bonding, this might be too difficult to
accomplish.
c) Protein function (transport, enzyme catalysis, etc...) may require flexibility in the three-
dimensional structure to allow for conformational change, and if protein three-dimensional
structure were held together by mostly covalent bonding, this might be too difficult to
accomplish.
d) All of the answer choices are rational explanations for why the three-dimensional structure of protein is driven and stabilized largely by noncovalent bonds rather than mostly covalent bonds
