D)The fibres can be stretched or extended,but are not flexible.

Question

Quizplus · Accepted Answer

Antiparallel β-sheets usually have all their hydrophobic residues on one side of the sheet, which creates a hydrophobic core that contributes to its stability. The direction of β-strands within the sheet is antiparallel, which means they run in opposite directions from N- to C-termini. The flexibility of the sheet depends on the amino acid composition and packing of the β-strands, but in general, β-sheets are more rigid than α-helices.
