For valid reasons, a cell would need to have the option to make or not make protein. Sometimes, the body may sometimes not need protein, making it vital for a cell to stop making it. In particular, the body may obtain a lot of protein from the diet, making it unnecessary for a cell to make others. Equally, the body may lack protein from diet, necessitating a cell to make some of these molecules to meet the body's demand. For these reasons, a cell should be flexible to make proteins when scarce and stop when plenty. Otherwise, the body may be overloaded or deficient with protein, leading to disorders.
