Altering protein structure a. can alter its function. b. can be caused by heating the protein. c. can have serious medical consequences. d. all of the answers are true.

The alteration in the protein structures can take place due to many reason. Once, the structure of the protein is altered, it cannot perform its function, as it cannot bind to the site for which it is designated.

Most of the biological processes use proteins in their completion. In case, the protein cannot perform its function, the metabolic process associated with that particular protein may stop and cause severe illness.

The heat can cause the denaturation of the proteins. The proteins are made up of amino acid sequences, the heat can break the peptide bond present between the amino acids present in protein, which can result in alteration of protein.

Hence, the correct answer is option (d). all of them are correct.

2%? i tried finding the exact sorry if it's not 100% correct ; -;

unicellular organisms, like bacteria, are able to perform all life functions within one single cell. multicellular organisms need many different types of cells to carry out the same life processes. each of these special types of cells has a different structure that it perform a specific function.
