Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Hemoglobin can be an effective protein when
A
it is folded in the right way
B
it is located on the membrane of your cells
C
it carries out fermentation
D
A and B
E
none of these
Explanation: 

Detailed explanation-1: -The hemoglobin molecule contains four separate folded peptide chains, which form a hydrophobic or water ‘repelling’ pocket around a heme group. The heme group is composed of a central iron atom complexed to four nitrogen atoms. Oxygen is capable of reversibly binding to the heme unit in a process known as oxygenation.

Detailed explanation-2: -Red blood cells containing faulty hemoglobin can become misshapen and rigid, making it difficult for them to pass through small blood vessels, slowing or blocking blood flow. This in turn can compromise oxygen delivery to different tissues and organs, causing damage and inflammation.

Detailed explanation-3: -Hemoglobin has a quaternary structure. It consists of two pairs of different proteins, designated the and chains.

Detailed explanation-4: -The function performed by the heme group depends upon the structure of the protein. In hemoglobin, the heme group serves to bind oxygen molecules. Hemoglobin is responsible for carrying oxygen from the air in the lungs to all the cells in the body via red blood cells present in the blood.
