1 Exam Prep #6 Membranes Name: ______________________________________________ 1. List the functions of membrane proteins.(Total 4 marks) 2. The diagram below shows which areas on the surface of a protein are composed of hydrophobic amino acids and which areas of hydrophilic amino acids. Where in a cell would the protein be located? A. In a nuclear pore B. In the space between the inner and outer mitochondrial membranes C. In the matrix of a mitochondrion D. In a phospholipid bilayer (1 mark) 3. Draw and label a diagram to show the fluid mosaic model of a biological membrane. (6)

1.3 Membrane Structure. Essential idea: The structure of biological membranes makes them fluid and dynamic. Above are models of a plasma membrane showing how it's fluidity allows lipid soluble molecules to move directly through the membrane.
