STRUCTURE OF PROTEINS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Why is folding so important in proteins?
A
It gives them a unique, functional shape.
B
It makes them look tidier.
C
The folding is random so is not that important at all.
D
It makes every protein molecule different from the next even if they are the same type.
Explanation: 

Detailed explanation-1: -Protein folding occurs in a cellular compartment called the endoplasmic reticulum. This is a vital cellular process because proteins must be correctly folded into specific, three-dimensional shapes in order to function correctly. Unfolded or misfolded proteins contribute to the pathology of many diseases.

Detailed explanation-2: -Each protein has its own unique sequence of amino acids and the interactions between these amino acids create a specify shape. This shape determines the protein’s function, from digesting protein in the stomach to carrying oxygen in the blood.

Detailed explanation-3: -Proteins are long chains in which hundreds to thousands of building blocks are arranged in a particular sequence. To carry out their biological functions, these chains must adopt precisely ordered shapes (termed structures) in a process called protein folding.

Detailed explanation-4: -The end result on the protein’s three dimensional structure holds a great deal of biological importance. The final structure of the protein exposes a number of channels, receptors, and binding sites, and affects how it interacts with other proteins and molecules.
