Question

Protein has definite shape in certain pH and temperature. what is the role of it during hydrolysis of fat protein and carbohydrates?

Answer 1

The structure of a protein is determined by its amino acid sequence. This in turn determines the secondary, tertiary and quaternary structures. The function of a protein, be it enzymatic, structural, signalling, is determined by its structure; hence an enzyme will have an active site which is where the substrate binds in order to be converted or modified into something else. The shape of the active site is dependent on the amino acid sequence and the folding of the protein molecule. Thus the ‘basic functioning’ of cells - their growth, activity, secretion, metabolism etc which is mainly brought about by enzymic activity is entirely dependent upon the structure of its proteins.
