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.
Yes, aquaporin is a protein that functions as a water channel in cell membranes.
Protein domains are distinct sections of a protein that have specific functions, such as binding to other molecules or catalyzing chemical reactions. Motifs are smaller, recurring patterns within protein sequences that also have specific functions. Both domains and motifs play crucial roles in determining a protein's structure and function in molecular biology.
The N-terminal region of a protein is the starting point of the protein chain, while the C-terminal region is the end point. These regions can have different functions and structures, influencing how the protein functions in the body.
Ferritin is a protein that functions to store iron in the body. Transferrin is a protein that transports iron in the blood.
The N-terminal region of a protein helps in targeting and directing the protein to its correct location within the cell, while the C-terminal region is involved in protein-protein interactions and stability.
Two functions of protein are growth and repair.

Yes, aquaporin is a protein that functions as a water channel in cell membranes.
The organelle that functions as a protein factory is the ribosome. Ribosomes are responsible for protein synthesis in the cell by decoding the messenger RNA (mRNA) and assembling amino acids into polypeptide chains.
The ribosome is a cellular organelle that functions in protein synthesis, building proteins based on instructions from messenger RNA molecules. It serves as the site for translation of genetic information from RNA into proteins.
