Which level of protein structure is most directly responsible for enzyme specificity?
Tertiary structure is the most important of the structural levels in determining, for example, the enzymatic activity of a protein.
What is most directly responsible for specificity of enzyme?
Which the following characteristics is most directly responsible for the specificity of a protein enzyme? The R groups of the amino acids in its active site.
How protein structure is involved in enzyme specificity?
Explain how protein structure is involved in enzyme specificity. The amino acid sequence of an enzyme determines its shape; how congruously the shape of its active site and the shape of the substrate fit together measures its specificity. 20. Enzymes use a variety of mechanisms to lower activation energy.
Which level of protein structure is most responsible for that proteins chemical properties?
While the amino acid sequence makes up the primary structure of the protein, the chemical/biological properties of the protein are very much dependent on the three-dimensional or tertiary structure.
Which level of protein structure is the most complex?
Quaternary structure
Quaternary structure would be the most complex structure as it involves the most components from separate tertiary protein structures.
What determines the specificity of an enzyme for its substrate?
Enzymes increase the rate of exergonic reactions by lowering the activation energy of the reaction. What determines the specificity of an enzyme for its substrate? For a substrate to bind to the active site of an enzyme it must fit in the active site and be chemically attracted to it.
What component of enzyme structure is responsible for specificity?
The apoenzyme is responsible for the enzyme’s substrate specificity.
What level of protein structure is affected by chemically straightening hair?
What level(s) of protein structure are affected by chemically straightening hair? Tertiary and quaternary structures. Why doesn’t hair stay straight forever after being chemically straightened?
What level of protein structure is created during protein synthesis?
Quaternary Structure of Proteins The quaternary structure describes the way in which the different subunits are packed together to form the overall structure of the protein.
Which of the protein structural levels shows the protein as a complete structure?
The quaternary structure describes the way in which the different subunits are packed together to form the overall structure of the protein.
What determines the primary structure of a protein?
A protein’s primary structure is defined solely by its amino acid sequence, and is constructred by peptide bonds between adjacent amino acid residues. Secondary structure results from hydrogen bonding along the polypeptide backbone, resulting in alpha-helices and beta-pleated sheets.
