Hemoglobin is a protein that binds to oxygen. it is only produced by red blood cells and it allows blood to transport oxygen throughout the body. what statement does this information best demonstrate? a. specialized cells that are grouped together and perform similar functions are called tissues. b. the proteins produced by cells have structures that are related to their function. c. proteins with similar functions to those produced in humans can be found in other species. d. proteins in specialized cells are the result of the expression of particular genes.

B.Proteins produced by cells have structures that are related to their function.

Explanation

Haemoglobin contains 4 polypeptide chains.In adults,they have 2alpha (a) globin chains and 2 beta (b) globin chains.Each polypeptide has a haem prosthetic group attached.A single haem bids one oxygen molecule.The 4 haemoglobin groups in every molecule of haemoglobin binds 4 oxygen molecules.

B. The proteins produced by cells have structures that are related to their function.

Explanation:

Hemoglobin is a protein which transports Oxygen in the blood from the lungs to all the tissues of the body.

This kind of protein is formed by linking up a number of amino acids into a polypeptide chain. A single amino acid is a protein which is also known as the 'residue'. These residues arrange themselves and interact within a protein to determine the protein's shape and contribute to its functionality.
