which statement best describes the molecular structure of protein, along with one of the functions of proteins?\nit is a straight chain hydrocarbon that can help fight disease.\nit is a complex, folded chain that helps regulate cell processes.\nit is a simple carbon, hydrogen, and oxygen molecule that creates movement.\nit is a chain of nucleotides, and forms muscle, bone, and ligaments.
Answer
Brief Explanations:
Proteins are complex macromolecules made of amino - acid chains that fold into specific three - dimensional shapes. They play crucial roles in regulating cell processes. Hydrocarbons do not describe proteins. Simple carbon, hydrogen, and oxygen molecules are not proteins. Chains of nucleotides are nucleic acids, not proteins.
Answer:
It is a complex, folded chain that helps regulate cell processes.
