What is a globular protein?
Q: What is a globular protein?
A: A globular protein is a common type of protein that is one of three types, along with fibrous and membrane proteins.
Q: How is the structure of a globular protein formed?
A: The structure of a globular protein is a result of protein folding, which involves polypeptide chains being folded into a compact sphere shape.
Q: Why are globular proteins soluble in water?
A: Globular proteins are soluble in water because of the hydrophilic (‘water-loving’) side chains that project from the outside of the molecules.
Q: What role do globular proteins play in metabolic reactions?
A: Globular proteins play an important role in metabolic reactions and can act as enzymes, messengers, transporters of other molecules through membranes, and regulators of other molecules.
Q: How do globular proteins differ from fibrous proteins?
A: Globular proteins can act as enzymes and messengers and have a compact, spherical shape, while fibrous proteins have a more elongated shape and are typically involved in structural functions.
Q: What are some examples of globular proteins?
A: Examples of globular proteins include myoglobin and hemoglobin, which are involved in oxygen transport in the blood.
Q: What is the function of hormones in biological processes?
A: Hormones transmit messages to regulate biological processes, such as insulin, which regulates blood sugar levels.
