Generally, the graph line will begin as a straight line when the substrate concentration is low. At very low substrate concentrations, the rate is proportional to the substrate concentration. As substrate concentration increases, it affects the enzymatic reaction, so the rate will change and the line will change.
Explanation:
Vestigiality is the retention during the process of evolution of genetically determined structures or attributes that have lost some or all of the ancestral function in a given species. Assessment of the vestigiality must generally rely on comparison with homologous features in related species.
