Give an example of a protein for each of the functions of proteins. (Support –Metabolism – Transport –Defense – Regulation – Motion)
Homework Answers
support protein - the main function is to provide mechanical support eg. keratin, collagen etc.
Metabolism - Enzymes are proteins that catalyze biological processes. eg. lipase that help in lipid metabolism, Amylase that is found in saliva
transport Protein -its function is to transport biomolecules. eg- hemoglobin that carries O2
Defence protein - involves in the immune response all antibodies are proteins. eg- fibrinogen is blood clotting protein
regulator protein - helps in regulating cellular and physiological activity. eg- insulin
motion proetins are same as transport proteins

Show and discuss one example of each of each of these protein classes: 1) Membrane Proteins, 2) Receptors, 3) Carrier Proteins. Here, elucidate the protein structure and function. So, what structural features of the protein allow it to function in this protein class capacity? (e.g. alpha helices are a common feature among many membrane proteins that allow them to respond to different external signals)

Hemoglobin consists of four globular proteins, each formed from a polypeptide chain. Each globular protein contains a nonprotein group with an iron ion. This iron ion binds to an oxygen molecule. Thus, every hemoglobin protein can bind four oxygen molecules. Select the correct statement about oxygen transport below. a. Myoglobin transports oxygen through the bloodstream to tissue. b. To carry oxygen, iron must be in its nonheme form. c. Erythrocytes contain abundant myoglobin for transporting oxygen. d. Hemoglobin is found...
