Concept explainers
(a)
Interpretation: The characterization of the actin protein in terms of its function classification has to be stated.
Concept introduction: Proteins play an important role in various biochemical processes. On the basis of functions, there are several major categories of proteins such as catalytic proteins, defense proteins, transport proteins, messenger proteins, contractile proteins, structural proteins, transmembrane proteins, storage proteins, regulatory proteins, nutrient proteins, buffer proteins and fluid-balance proteins.
(b)
Interpretation: The characterization of the myoglobin protein in terms of its function classification has to be stated.
