Which type of protein is primarily involved in transport functions?
Globular proteins are primarily involved in transport functions.
What is the main function of enzymes?
Enzymes catalyze biochemical reactions.
Which protein category do antibodies belong to?
Antibodies belong to globular proteins.
True or False: Structural proteins are involved in signaling processes.
False
What is the role of structural proteins?
Structural proteins provide support and shape to cells and tissues.
Which protein type is often involved in hormone functions?
Globular proteins are often involved in hormone functions.
What is keratin commonly associated with?

True or False: All globular proteins have a quaternary structure.
False
What role do hormones play in the body?
Hormones regulate various physiological processes.
What is the primary function of collagen?
