Primary structure refers to the amino acid sequence of a polypeptidePrimary structure refers to blank. Secondary structure refer
s to blank created by blank. Tertiary structure refers to blank. Primary structure is determined by blank whereas secondary and tertiary structures are determined by blank. Primary structure is stabilized by blank between blank, whereas secondary structure is stabilized by blank between blank while tertiary structure is stabilized by blank.. Secondary structure
<h2>Protein exists in different forms- primary, secondary, tertiary and quaternary structure.</h2>
Explanation:
Primary structure of protein consists of amino acids joined by a peptide bonds. Peptide bond exists as covalent bond. Secondary structure of protein is stabilized by hydrogen bonds. Tertiary structure is stabilized by hydrophobic interaction, electrostatic interaction and disulphide bonds. Similarly, quaternary structure is stabilized by non-covalent interactions and disulphide bonds. So, each structure of protein is stabilized by different types of bonds.
The substrate and the active site both need to fit together perfectly in order for the enzyme to work properly. If their shape is changed, typically through heat or a change in pH, the enzyme will not work.
The hole reason for natural selection is to keep the Eco system in balance take something away it will fall apart or if you put to much of something the same thing will happen.
The answer would be letter A. globular cluster. This group of very old stars that are clustered together in a spherical in shape and can contain from 10,000 to several million is called a globular cluster. In our galaxy, there are 150 globular clusters.
