Copy the table and complete both the columns. The table shows some functions of proteins, with examples of proteins that carry out these functions. Function Example structural 1 2 enzyme insulin haemoglobin and myoglobin defence actin and myosin storage

Function Example structural 1. Keratin 2. Collagen enzyme Maltase lower the blood sugar level insulin oxygen transport haemoglobin and myoglobin defence immunoglobulin muscle contraction actin and myosin storage ferritin Collagen is the structural protein found in the connective tissue. Maltase is an example of enzyme that breaks down starch. Insulin is secreted from the beta cells of islets of Langerhans and regulate blood sugar level in the body of an individual. Immunoglobulin is an example protein that helps in defence mechanism. Ferritin is an example of storage protein. Actin and myosin help in the muscle contraction in the body of an individual. Hemoglobin and myoglobin help in the oxygen transport in the body of an individual.
