Which best describes the shape of myoglobin, which in many ways is a typical protein? a complex three-dimensional shape formed from many twisted helixes a cylindrical shape that forms from a single twisted helix a straight chain, like beads on a straight piece of string a highly-branched chain, much like the branches of a maple tree

A complex three-dimensional shape formed from many twisted helixes best describes the shape of myoglobin, which in many ways is a typical protein.
