C) globular
D) helical
E) membrane

Fibrous proteins, such as collagen and keratin, are unique in their structure and often have properties that allow them to be strong and flexible. They are composed of long, linear chains of amino acids that are bundled together to form strong fibers. This structure provides strength while the linear nature of the chains allows for flexibility. Macromolecular proteins may be large, but they do not necessarily possess the same properties as fibrous proteins. Globular proteins are compact and have a spherical shape, while helical proteins have a spiral shape. Membrane proteins are embedded in cell membranes and often have unique properties, but they may not necessarily be both strong and flexible.
