Beta pleated sheet. 17 (B400U10-1) Turn over. 17 to move substances across the cell surface (e.g. Cilia can be found on cells lining the trachea. These cells help to move mucus and trapped particles away from the lungs). Organelles found only in plant cells: The . cell wall. surrounds the outside of a plant’s cell membrane, and also attaches cells to their neighbours. GCSE Biology (Science) revision covering Globular and Fibrous Proteins. Topics include Haemoglobin, amino acids, Collagen, The Primary structure of collagen, The Secondary/Tertiary Structure of Collagen, The Quaternary Structure of Collagen
The pleated sheet is stabilized by hydrogen bonds between the amine groups of one chain and the carbonyl groups of an adjacent chain. Tertiary Structure The tertiary structure of a polypeptide or protein is the three-dimensional arrangement of the atoms within a single polypeptide chain.
