Contractile Proteins - are responsible for movement. Examples include actin and myosin. These proteins are involved in muscle contraction and movement.
Enzymes - are proteins that facilitate biochemical reactions. They are often referred to as catalysts because they speed up chemical reactions. Examples include the enzymes lactase and pepsin. Lactase breaks down the sugar lactose found in milk. Pepsin is a digestive enzyme that works in the stomach to break down proteins in food.
Hormonal Proteins - are messenger proteins which help to coordinate certain bodily activities. Examples include insulin, oxytocin, and somatotropin. Insulin regulates glucose metabolism by controlling the blood-sugar concentration. Oxytocin stimulates contractions in females during childbirth. Somatotropin is a growth hormone that stimulates protein production in muscle cells.
Structural Proteins - are fibrous and stringy and provide support. Examples include keratin, collagen, and elastin. Keratins strengthen protective coverings such as hair, quills, feathers, horns, and beaks. Collagens and elastin provide support for connective tissue such as tendons and ligaments.
Storage Proteins - store amino acids. Examples include ovalbumin and casein. Ovalbumin is found in egg whites and casein is a milk-based protein.
Transport Proteins - are carrier proteins which move molecules from one place to another around the body. Examples include hemoglobin and cytochromes. Hemoglobin transports oxygen through the blood. Cytochromes operate in the electron transport chain as electron carrier proteins.

What are the functions of an integral protein found in the cell membrane?
The functions can vary greatly, the fact that its an integral protein limits the functions but there are still many different functions. Ill go through a few functions of integral transmembrane proteins. Transportation. Integral proteins can transport molecules and ions through the membrane, facilitated or active transport are two such transport functions. The protein can also act as ion channels which help the cells to keep the ion gradient at a good level (varies greatly for different ions). The protein can also act as receptors for different hormones or neural signals. The integral proteins can also be cytoskelleton, which function is to connect different cells to eachother, or they can be flagells, villi or microvilli.
Why must RNA be made during protein synthesis?
RNA must be made during protein synthesis because protein synthesis needs to go through this process in order to transfer organelles and the functions of DNA
