Some proteins are constitutively secreted from the cell because they are continuously needed to maintain the process of the cell. Whereas some proteins are needed only when the stimulus is received, therefore they are retained until their release is signaled for by a messenger.
Proteins are the polymers formed of amino acid monomers. These are the most essential nutrient required by the body. Proteins are involved in the building and repair of the body. Proteins can have a structural, functional or a catalytic role inside the cell.
A stimulus is any signal that triggers any organism to perform a certain action or process. The stimulus can be in the form of touch, smell, or even any thought.
